System Configuration
For a WARR, if you plan to move the receiving antenna 0.1m further apart from the fixed
transmitting antenna, set the step size to 0.1m.
6.1.4 Sampling Interval
Temporal Sampling Interval defines how often the GPR wave is sampled at the GPR receiver,
to accurately capture the resulting signal waveform. It is expressed as a time interval, in
picoseconds, between points on a trace (1000ps = 1ns). Antenna frequency affects the
sampling interval; higher frequencies are sampled at a finer time interval than lower frequencies
(Figure 6-5) to accurately capture the resulting waveform.
Figure 6-5: Low frequency signals require a longer sampling interval (left), whereas high frequency signals require a
shorter sampling interval (right)
Press Sampling Interval to display the screen shown in Figure 6-6, where you can set this
value.
