General information about
recorded file includes: Operator, Location,
Date of record; Dielectric constant of
surveyed material; Device used for
surveying; Time window at time of survey;
Trace count in file; X & Y for files recorded
with a distance measuring device.
Hz – Hertz, measurement unit for frequency. Radio Wave – Electromagnetic wave
with frequency ranging from 30Hz to 300GHz. For GPR from 10MHz up to 3GHz.
Radar – A system that uses radio waves to detect objects. Main components &
signal flow: Transmitter ->Transmission antenna -> Receiver Antenna > Receiver
data processor. Frequency Bandwidth – The
spectrum of the radar’s transmitted radio waves’ frequencies. Central
Frequency Transmitted waves at peak power (usually the center of the frequency
spectrum). UWB – Ultra Wide Band radar that transmits over a frequency
bandwidth > 500MHz.
WPR & Time-domain WPR State- of-the-art high resolution radar with low power consumption. Survey Sounding – The act of using GPR technology for object detection/determination. Radargram – Image produced by a radar. SEG-Y – General purpose file format for recording geophysical data from 1973. ERAD – open radar format optimized for small data storage. Time Window – Operational window of the receiver antenna. Penetration Depth Theoretical maximum depth achieved during a given time window and a material’s dielectric constant.
Dielectric Constant – Measure of a material’s ability to store electrical energy in an electric field. Attenuation – Reduction in GPR signal amplitude caused by energy dissipation in a material. Dynamic Range – Ratio between the max amplitude signal recordable by GPR and its noise floor. GPR Trace – Sequence of sample points collected by the receiver that indicate time variation of the amplitude of the recorded signal (in a given time window).
Resolution – Smallest
detectable difference/object
in
a
surveyed
material/soil/wall.
Gain – Signal amplification.
Background Removal –
Adaptive cancellation of the
effects of the surveyed
material.
DC Drift – Low frequency noise
causing the signal to drift from
the center line.
Pulse – Energy packet emitted
from the transmitter antenna.
Its properties are length,
power and rise time – a
measurement of how fast a
pulse achieves peak power.
