Important Safety Instructions
WARNING! Do not remove any part of the product enclosure or create an opening in the produce enclosure in any way. The risk of fatal electrical shock exists with any exposure to the internal product components. Further, any opening or modification of the enclosure by any non-Dynetics personnel voids the product warranty and can only be reinstated by Dynetics in writing.
The GroundAware™ product should only be used with the power and data cables supplied with the unit by Dynetics. Failure to use provided cabling may result in damage to the unit and an increased risk of electrical shock.
Safe Usage
Dynetics recommends that at least two people be used to move the unit. The
unit should only be mounted by qualified personnel using the appropriate
safety lanyards to prevent unrestrained unit fall should the mounting fail.
The mounting fixture, power receptacle, and data receptacle used with the unit
should be appropriately grounded by a qualified electrician.
VERY IMPORTANT: GROUNDWATER IS A RADIATING DEVICE WITH RF HAZARDS. INSTALLATION AND OPERATIONAL PROCEDURES MUST ENSURE THAT NO HUMANS OR ANIMALS PASS WITHIN FOUR AND ONE-HALF METERS (4.5 m) OF THE UNIT WHILE IT IS POWERED.

**General Description and Specifications
**
GroundAware™ 360 is a user Reconfigurable Surveillance Sensor that detects, tracks, classifies and provides actionable information relevant to objects within a 360° field of view up to One kilometer from the sensor. This capability is implemented via the interoperation of four sub-systems:
The radar sub-system transmits S-band radio frequency signals, digitizes and processes the received returns, identifies detections, clusters detections to identify tracks, and associates track with feature data that can be used to classify the object. The radar can be configured to use three different waveforms, based on the installed site, which will be explained in further detail in later sections. This manual should be used with radar subsystem model number 10037200.
The server sub-system receives track data, receives and processes classification data, hosts the GoogleMaps-based user interface, and implements external sensor (e.g. single/dual band PTZ camera, unattended ground sensor, etc) integration. Server hosting of the user interface includes managing user- defined alert zones, per-zone alerting criteria, and the per-zone violation log. Commodity grade desktop or laptop computers may be used to execute the server sub-system software.
The client sub-system renders the GoogleMaps user interface for each unique
browser session. Users may maintain their own zoom and view settings while
sharing zone
definitions, alert criteria, and camera control with other users. The user
interface is browser-agnostic but works best with Mozilla Firefox. While the
client software is executed on each user’s machine within a web browser, it is
provided upon authentication and managed by the server sub-system software.
The optional interface sub-system provides a cellular data link, optional use network interfaces, and independent radar power on/off control. The interface sub-system also includes the cabling, encoder, and power supplies required to integrate external cameras or other sensors. This sub-system is self-contained in an environmentally sealed enclosure with external switches and connectors as required by the customer.
GroundAware™ enables a customer to use the system in an environment where the
interface is continually monitored by personnel on desktop or mobile devices,
or in an
an unmonitored environment where personnel can be alerted to intrusions based
on user-defined criteria.
Figure 2-1 below illustrates how the GroundAware™ system and sub-systems
interact and what is typically provided by Dynetics and by the user/reseller.
NOTE: Optional
integrated cameras and other sensors not shown.

Specifications
The GroundAware™ system is a sophisticated, multi-channel digital beam-form
device that utilizes state-of-the-art Direct Digital Synthesis (DDS) waveform
generated digital signal processing to detect and very accurately track small,
slow targets minimizing false alarms. The GroundAware™ design has been refined
by Dynetics and user testing across the United States at various critical
infrastructure facilities, each unit is integration tested before delivery and
verified to meet the specifications enumerated in Table 2-2 below.
NOTE: These specifications only apply to the RaSub-System.

TABLE 2-2 GroundAware™ System/Sub-System Block Diagram
Installation
The GroundAware™ system is very easy to install and prepare for configuration
and operation. As illustrated briefly in previous sections, installation falls
into three fundamental phases: mechanical, electrical, and data.
Mechanical installation of the system includes mounting the unit such that it
is horizontally level and perpendicular to the center point of the area to be
monitored. The unit includes carrying handles on each side to aid in the
recommended two-person emplacement of the system.
An electrical installation includes connecting the unit to a maximum 35 Watt, 24 VDC, POE injector grounded alternating current source using a shielded ethernet cable. Optionally, the unit may be powered through the switch in the interface sub-system as described previously. Any additional switches utilized in the provision of power to the system (e.g. installed by the customer) should be rated for the type and quality of power specified.
Data connectivity installation includes connecting the unit to an IP4/IP6
network through which connectivity to the server sub-system can be obtained.
The unit maybe
connected to the server sub-system network by several different means such as
wired 50directly, cellular, Wi-Fi extending antennas, etc. based on user
requirements.
Given a basic understanding of system connectivity, installation and startup should proceed as follows, given a basic three sub-system setup:
- Mount the radar sub-system unit mechanically per the customer site requirements and preparations.
- Connect the radar sub-system unit to the IP4/IP6 server sub-system network using the means required by the customer site.
- Connect and power on the server sub-system on the same IP4/IP6 network as the radar sub-system.
- Connect the radar sub-system to commercial power that meets the previously provided specifications.
- Wait approximately 90 seconds before proceeding to the activities described in Section 3.
**Section 3**
Operation
This section assumes that the precautions and setup steps of the previous two sections have been read, understood, and followed. If any of the material or steps from sections 1 and 2 have been skipped or poorly understood, please pause and review the information and re-perform whatever steps may be necessary to ensure that GroundAware™ is properly and safely installed, powered, and connected before the activities of this section are performed.
Configuration
GroundAware™ may be generally configured by the user for three modes of
operation: short, medium, and long-range. Table 3-1 below specifies the
parameters of interest for each one of these modes.
Once the desired operational mode has been determined from the information provided in Table 3-1, the following steps should be performed:
- From the server sub-system, connect to the radar configuration page.
- Select and save the configuration file corresponding to the radar sub-system mode to be used.
- Command the radar sub-system to begin radiating.
Note: GroundAware™ has been UL certified for operation in the three modes
described above and each unit is tested by Dynetics in each of these modes
prior to delivery.
Additionally, each unit will be calibrated on-site by Dynetics personnel to
detect and track a 2m tall, 92kg human at a distance of 500m assuming at least
a 10m emplacement height and unobstructed line of sight to the target.
User Access
At this point, the desired operational mode should be set, the radar should be
radiating, and any site-specific calibration by Dynetics personnel should be
complete.
User’s Guide
The GroundAware™ user interface is an extended instance of GoogleMaps and is very intuitive to use by anyone who has experience with web-based mapping websites. The traditional controls for zoom, pan, etc. work the same as with a standard GoogleMaps website. Dynetics will provide training as necessary to allow operators to monitor the system using this interface and configure alarm zones to their preferences.
