The EdgeTech 3400 Sub-Bottom

Profiler System is a wideband

frequency modulated (FM) sub-

bottom profiler utilizing EdgeTech’s

proprietary Full Spectrum CHIRP

technology to generate high-

resolution images of the sub-

bottom stratigraphy in oceans,

lakes, and rivers and provide

excellent penetration of various

bottom types. This system provides

for standard sub-bottom profiling operations, including real-time

reflection coefficient measurement or a unique “Pipeliner” mode that provides for optimal location and

imaging of buried pipelines. These unique capabilities allow surveyors to collect complex analytic data

using linear system architecture to measure sediment reflection and analyze sediment type

determination. Additionally, the system has discrete transmit and receive channels, allowing for

continuous data collection, resulting in a high ping rate that is particularly important for construction and

pipeline surveys. The system includes one of several 3400 vehicle types, cable, and a topside processor

(portable or rack-mounted topside) running EdgeTech’s Discover 3400 sub-bottom acquisition and

processing software. Amplifiers are included or are options for certain 3400 system types.

The 3400 is available in five variants. They are:

3400 Sub-Bottom Profiler: This hydrodynamic configuration hosts dual 2-16 kHz transducers and PVDF receiver array configuration. The system is designed to be towed or can be pole-mounted off the side of a vessel with the purchase of a pole-mounting kit.

3400 OTS LF Sub-Bottom Profiler: This over-the-side configuration is designed to be pole-mounted off the side of a vessel. It consists of a dual 1-10 kHz transducer and PVDF receiver array configuration. It provides for deeper water operations than the towed 3400 Sub-Bottom profilers. This vehicle type supports an amplifier option.

3400 OTS Light Sub-Bottom Profiler: This shallow-water configuration hosts a 2-16 kHz transducer and PVDF receiver array configuration, offering deeper penetration than the UltraLight 3400. It is designed to be pole-mounted and can be used on small vessels.
3400 OTS Ultra-Light Sub-Bottom Profiler: This shallow water configuration comes with a single 4-24 kHz transducer and PVDF receiver array configuration. It is designed to be polemounted and can be used on small vessels.
3400-512E Sub-Bottom Profiler: This hydrodynamic configuration hosts two combined transducers that support a frequency range from 0.5-12kHz and a PVDF receiver array configuration. The system is designed to be towed by a vessel and includes an amplifier.

1.1 Key Features of the 3400 Sub-Bottom Profiling System
· CHIRP Transmission · Dual (Wideband) Transmitters (3400 and 3400 OTS LF Sub- Bottom Profilers) · Dual Frequency Transmission · Enhanced Sub-Bottom Multi- Channel PVDF Receivers · Reflection Coefficient Calculation · Sub-Bottom Pipeliner Mode · Surface Echo Attenuation · Pulse Library Tailored For Different Survey Applications · Built-in Motion, Pitch, Roll, Heave, and Depth Sensors
1.1.1 CHIRP Transmission
The 3400 leverages compressed high-intensity pulse sweep (CHIRP) transmission technology to process and display detailed sub-bottom sonar imagery. CHIRP technology accomplishes this by transmitting wideband sound pulses that are linearly swept over a full-spectrum frequency range. Different frequencies compensate for the inconsistencies in the way different layers, objects, and materials reflect sonar pulses providing more penetration and more detailed data.

1.1.1.1 Advantages of Full Spectrum CHIRP Technology
EdgeTech’s Full Spectrum CHIRP technology has several distinct advantages over conventional subbottom profiling systems:
· Separate acoustic projectors and receivers that allow for simultaneous transmission and reception of acoustic signals.
· High repeatability of the transmitted signals to enable sediment classification · High signal-to-noise ratio (SNR) for improved acoustic imagery · High resolution for measurement of fine sediment layering · Additional processing gain for energy efficiency · Gaussian-shaped amplitude spectrum for improved resolution and Uniform-shaped sweeps for
greater sediment penetration · Reduction of side lobes for minimal destructive signal scattering caused by the sediment when
profiling near the bottom
All these advantages are discussed in detail below.
Separate Acoustic Projectors and Receivers
The 3400 Sub-Bottom Profiling System uses acoustic projectors and receivers to transmit and receive frequency swept acoustic pulse signals. The projectors are wideband piston-type transducers, and the receivers are composed of polyvinylidene difluoride (PVDF) hydrophones. The transducers are mounted in the forward section of the tow vehicle or hull mount, and the hydrophone arrays are mounted aft, which are designed for profiling at ship speeds up to seven knots.
The use of separate transmitting transducers and receiving hydrophone arrays preserves linearity and allows the simultaneous transmission and reception of the acoustic signals. The transducers and hydrophone arrays are mounted beneath acoustic baffles, which minimize direct path, mounting structure, and surface reflections. A digital preamplifier amplifies and converts the analog signal into a digital bitstream. The digitally received signals are transmitted through a tow cable to the surface.
High Repeatability
The FM pulses are generated by a digital-to-analog (D/A) converter with a wide dynamic range and linear transmit components. This allows the energy and amplitude characteristics of the acoustic pulses to be precisely controlled. This precision produces the high repeatability and signal definition required for sediment classification.
The frequency range of operation is determined by the acoustic characteristics of the transmitter transducers and receiving hydrophone arrays mounted on the tow vehicle. Each tow vehicle transmits acoustic pulses with different center frequencies and bandwidths. The operator makes the pulse selection to achieve the best imagery.

1-4
High Signal-to-Noise Ratio
High Signal-to-Noise Ratio (SNR) is critical to providing world-class quality sub-bottom imagery. To that end, EdgeTech optimizes all aspects of sub-bottom systems to achieve the best possible quality. These optimizations include the use of (A) wide bandwidth and high power amplifiers to optimize energy in the water; (B) wide bandwidth transmitters and hydrophone arrays; (C) baffling of receive hydrophones to suppress surface reflections; (D) large aperture PVDF hydrophones to make receive sensitivity more directional and suppress noise by rejecting signals from undesired angles of arrival; (E) conventional chirp pulses and proprietary variants which optimize SNR, reduce sidelobes, enhance system resolution; (F) electronics optimized to theoretical Johnson Thermal Noise limits (receive signals are digitized at the towfish).
High Resolution
EdgeTech pulse processing capabilities result in a high temporal resolution. This high resolution enables the measurement of fine layering in the sediment, an important factor in sediment classification, as it provides a more realistic picture of the true geologic variability of the seafloor and an accurate determination of the depositional processes.
Additional Processing Gain
EdgeTech CHIRP technology achieves a signal processing gain over the background noise. This gain is approximately ten times the log of the time- bandwidth product. This improvement is due to the signal having a time duration longer than the inverse of the bandwidth, thus increasing signal energy without increasing the power of the outgoing pulse. To equal the typical performance of the full spectrum sonar pulse, conventional pulse sonar would have to operate at a peak pulse power of 100 times greater than a full spectrum pulse with a time-bandwidth product of 100.
Gaussian Shaped Amplitude Spectrum Outgoing Pulse
The outgoing pulse’s amplitude spectrum is chosen to be approximately Gaussian in shape to limit the sidelobe level and temporal resolution losses due to attenuation. As a wavelet with a Gaussian-shaped spectrum is attenuated by the sediment, energy is lost, but its bandwidth is nearly preserved. Therefore, even after being attenuated by sand, the acoustic pulse has approximately the same resolution as an unattenuated pulse.
Reduction of Side Lobes
Full Spectrum CHIRP technology reduces the side lobes in the effective transducer aperture. The sweep frequency’s wide bandwidth has the effect of smearing the transducer’s side lobes and thus achieving a beam pattern with virtually no side lobes. The effective spatial beam width obtained after processing a full spectrum 2­10 kHz signal, for example, is 20 degrees measured at the -3db points.
1.1.2 Dual Wideband Transmitters (3400 and 3400 OTS LF Sub-Bottom Profilers)
The EdgeTech 3400 and 3400 OTS LF Sub Bottom Profilers come standard in a dual transducer configuration, providing an increased source level and beam pattern.

1.1.4 Enhanced Sub-Bottom Multi-Channel PVDF Receiver
EdgeTech’s PVDF (polyvinylidene fluoride) receivers have advantages over other systems. The segmented panel provides different operation modes, from sub- bottom profiling to very specific applications like Pipeliner Mode. The receivers provide greater sensitivity and greater spatial acoustic rejection over other receivers. They also exhibit a flat sensitivity response over a wide bandwidth.

1.1.5 Reflection Coefficient Calculation
Discover 3400 Sub-Bottom Software can calculate reflection coefficients that aid in bottom sediment classification. The configuration procedure to do this adjusts the system gain constant so that the reflection coefficient provides an estimate of the ratio between the pressure amplitude of the pulse striking the seafloor and the amplitude of the reflected pulse. These values can then be compared with the known values of the local seafloor to classify the composition of the surveyed area. Detailed instructions on reflection coefficient calculation are found in the 3400 SOFTWARE MANUAL.
1.1.6 Sub-Bottom “Pipeliner” Mode
In conventional Sub-Bottom configurations, two hydrophone arrays are mounted parallel in the AlongTrack direction, which gives a narrow along-track beamwidth and a wider across-track beamwidth. In these Sub-Bottom systems, the surveyor had to manually switch the vehicle’s hydrophone position to achieve the wide Fore/AFT beam configuration suitable for pipeline detection.
In EdgeTech’s new pipeline detection configuration, a single transverse hydrophone sensor gives a wide along-track beamwidth, accentuating the pipeline’s parabola.

Figure 1-8: Interpretation: Pipeline and Cable Detection
The 3400 Sub-Bottom Profiler has a unique “Pipeliner Mode” feature that utilizes the parabolic acoustic shape created by the smaller narrow receive PVDF panel, that is wide in the Along Track Direction (parallel to the direction of travel and running Fore/Aft) and narrow in the Across Track Direction (normal to the direction of travel and running Port/Starboard). When approaching a buried cable or pipe (normal incidence), the wide Fore/Aft looking beam (Pipeliner mode) provides the ability to detect the object at greater ranges. As the 3400 continues to approach the object, not only does signal strength increase, but

the acoustic travel time will decrease. When plotted, the increasing strength and decreasing travel time create a parabolic shape that reaches an apex when the distance between the 3400 and the object is minimized. The object creates the second parabolic leg as the 3400 moves away. Multiple passes can further refine the position and triangulation.
Pipeline, cable detection, and Depth-of-burial (DOB) surveys seek to visually identify the signature hyperbolas, indicating a cylindrical object at the cross point between the cable route and the survey track. Narrow-beam systems may miss target pipes or cables in heterogeneous environments because they are focused on a single return as opposed to the graphically “increasing/decreasing” shape that visually highlights the path leading to and away from the target.
EdgeTech’s Discover Sub-Bottom software allows the surveyor to automatically switch between the 3400’s dual apertures when switching to a transmit pulse designed to provide a very high ping rate (up to 30 Hz) for better detection and measurement of the shallow buried pipe/cable.
The Pipeline Mode feature of the 3400 can also detect boulders, UXO, buried hazards, or other debris for site clearance and route surveys.
The echo data’s diffraction hyperbolas are generated by running survey lines perpendicular to the pipe/cable crossings. Multiple crossings might be necessary to meet the survey requirement of AlongTrack data density. Higher pipeline position accuracy is achieved by having the sonar close to the seafloor (2-5m).
Configuring a 3400 system to Pipeliner Mode is a software configuration with no hardware modifications or changes required. Detailed Instructions on configuring the 3400 sonar subsystem to this mode are found in the Configure the 3400 to Pipeliner Mode section of the DISCOVER 3400 SOFTWARE MANUAL.
1.1.7 Surface Echo Attenuation
The sensor assembly is designed to mitigate surface reflections. This is achieved through physical and material collaborations between the sensors and the support structure.
1.1.8 Pulse Library Tailored for Most Survey Applications
The 3400 pulse library includes both FM and BOOST pulses to collect the best datasets on the various seafloor types. BOOST pulses emphasize the low end of the bandwidth, which exhibits better deep water performance over standard Gaussian-shaped pulses.
1.1.9 Built-in Motion, Pitch, Roll, Heave, and Depth Sensors
3400 vehicles have a SBG AHRS that provides heave, pitch, and roll to the system. These values are displayed and real-time in Discover. The 3400 does not use heading, and the AHRS requires no customer calibration.

3.0 3400 SETUP AND ACTIVATION
Setup and testing of the EdgeTech 3400 Sub-Bottom Profiling System involve: 1. Unpacking, inspecting, and connecting the system components 2. Connecting a navigation system and external sonar systems, if required 3. Activating the system 4. Verifying operation using Discover Sub-Bottom
This section provides instructions on how to perform these tasks and provides information on how to deploy and tow the 3400 Towfish.
3.1 Standard 3400 Towfish Setup and Activation
3.1.1 Unpacking and Inspection
The 3400 Towfish, Portable Topside, and Tow Cable are shipped in separate, reusable, heavy-duty transport cases. Essential cables and documentation are also included. Before unpacking the system components, inspect the shipping containers for any damage. Report any damage to the carrier and EdgeTech. If the shipping containers appear free of damage, carefully unpack the components and inspect them for damage. Review the packing list and verify all the listed items are included. Again, if any damage is found, report it to the carrier and EdgeTech. If any items are missing, immediately contact EdgeTech. Do not install or operate any equipment that appears to be damaged. Although the items shipped may vary, depending on the customer’s requirements, the 3400 Sub-Bottom Profiling System typically includes the following:
· 3400 Tow Vehicle · 3400 Portable Topside · Optional Laptop · AC power cords (1) · Ethernet cable · System Recovery Drive · Electronic Manuals
After unpacking the system components, safely store the shipping containers for later use, including any packing materials. When transporting or storing the system, all items should be packed in their original shipping containers in the same way they were originally shipped. Always store the system in a dry environment when not in use.

3.1.2 Power Requirements
The 3400 power requirements are 120­220 VAC and 50/60 Hz, and the input voltage is auto-sensing.

3.1.2.1 Use of an Uninterruptable Power Supply
The power source should be continuously free of high amplitude, high-frequency transients, as this type of interference could cause degraded performance or damage to the equipment. An Uninterruptable Power Supply (UPS) with power surge protection is recommended for powering the equipment.
Whether or not a UPS is used, the power source should never be the same as that being used to power electric motors, such as pumps and winches, on the survey vessel.

3.1.2.2 Changing to a Non-US Power Plug

An AC power cord is provided for connecting the 3400 Portable Topside to a standard U.S. 3-pronged outlet. For non-U.S. power outlets, you can modify this cord by cutting off the 3-pronged plug and attaching the appropriate plug.

The 3400 Sub-Bottom Profiling System accepts all standard National Marine Electronics Association (NEMA) 0183 message sentence formats from a connected Global Positioning System (GPS) or Integrated Navigation System. The devices are connected to the system by plugging them into the COM A or COM B serial ports located on the rear panel of the 3400 Topside. Optionally they could be connected to the serial port of the computer as well. Configuration instructions are found in the DISCOVER 3400 SOFTWARE MANUAL.

3.1.4 3400 Portable Topside Placement
The topside should be located and set up in a dry, sheltered area that is protected from weather and water spray. The unit requires an environment where the temperature is consistently between 0°C and 45°C (32°F and 113°F). Furthermore, avoid areas of direct sunlight, especially in tropical environments, as heat buildup could damage the equipment, and glare could hinder the user’s ability to see LCDs, digital displays, and status indicator lights. The processor’s location should allow users to communicate directly with the deck crew that is handling the vehicle. Secure the topside processor in place, using tie-downs if necessary, near the required AC power source. Also, ensure that there is ample room behind the rack for connecting the cables. Support the components inside the rack using appropriate mounting brackets and secure the front panels using standard panel mounting hardware.
WARNING! Never operate or open the unit where it can become wet from sea spray or precipitation. Injury or death from electric shock can occur as well as damage to the equipment.

3.1.5 Cable Connection Tests

3400 vehicle and tow cables must be mated together completely throughout deployment. There should be no exposed pins on the output connector and no exposed threads on the connector locking sleeves to produce a safe, waterproof seal over the connectors. Cable connection tests should be conducted the first time any new tow cable, vehicle cable, or cable component is introduced to ensure the vehicle and tow cable are safely mated throughout deployment. Tests should occur periodically during the system’s life cycle as part of regular maintenance.

There are two vehicle cable types your 3400 will have depending on when your system was purchased. The first and newer type is a blue cable with red connectors, stainless steel locking rings and a rubber ball stopper. The second type is a yellow cable with red connectors and rubber type O-rings. The tests are the same for both cable types.

Figure 3-2: Blue Vehicle Cable Type

EdgeTech suggests two tests. The first is to mate the tow and vehicle cables and visually inspect that no connector pins are exposed, and the locking sleeves mate completely with no exposed threading. The second, is to ensure that the connectors will stay mated throughout deployment. This test involves lightly disconnecting the connectors exposing the connector pins, mating the connector locking sleeves, and then opening the connectors

3-99 and check to see if the connector pins are still exposed. The connectors locking sleeves should push the pins into the connector and keep them there.
WARNING! The vehicle and tow cables must be mated together completely with no exposed pins between the connectors and no exposed threads in the locking sleeves throughout deployment. Exposed energized connectors can result in injury or death of personnel, and equipment damage or loss can occur due to electric shock. Cables and connectors should be tested regularly. To test that the connectors and locking sleeves properly mate: 1. Plug the vehicle cable into the tow cable. Visibly inspect the connection. The output pins should not be exposed.
