GPR* Equipment Configuration
(*) GPR stands for Ground Penetrating Radar
This pages describes the configuration of the sled that carries
the GPR and the GPS. The GPR and GPS are connected to the same computer,
to attach a position measurement to every GPR reading.
Ground Penetrating Radar
The GPR has one main unit and antennas. The main unit generates the pulses
and provides controls to define he pulse rate and depth reach. It also
outputs the analog echo signal and the trigger for conversion.
There are two antennas: with a center frequency of 500 MHz and
1 GHz, respectively. The antennas are connected to the main unit via a
10 meter cable for operations with the antenna inside the sled, and outside,
with manual control of the antenna coverage.
