Technical Parameters
Terravision Exploration’s shallow system uses bistatic, half wave dipole, resistively loaded antennas linked to a high-speed receiver and recording console. The high frequency configurations are useful for high resolution surveys of the shallow sub-surface up to depths of 10m, in ideal conditions they have been known to penetrate up to 25m depth! The high frequency systems boast the following antennas:
​
​
​
​
Bertha Transmitter: 20MW “monopulse”: Effective penetration depth is 200m
-
The capacity of the transmitter can be from 1 to 10-20 Megawatt
-
Working frequency range (MHz) 1-250
-
Number of samples per scan (ns) 512, 1024, 2048, 4096
-
Antennas can be 0.3m, 1m, 1.5m, 3m, 6m, 10m and 15m.

Hardware
The Radar uses different sized antennas, transmitters, receivers and consoles. The Radar is configured as follows:
-
A Transmitting Antenna
-
A Receiving Antenna
-
A Transmitter
-
A Receiver
-
Receiving Console
-
Laptop with proprietary software
Scanning to different depths or achieving certain resolutions, requires the same configuration with component parts changed to suit the target and objective.
