This radar device is particularly effective in detecting landmines
in agricultural land where the mines are of the anti-personnel (AP)
types. The spread of the land and challenging terrain normally pose
challenges to the conventional methods but not for a system based
on the Greatcore GDM1 system. Moreover the thoroughess, accuracy
and speed achieved from our system has proven unmatched.
can be applied to the three critical problems that hinder the ongoing
operations in the Middle East: IEDs and AP landmines buried under
road surfaces, embedded inside building walls and hidden within
otherwise innocuous objects that litter the roadsides.
Results of mine imaging tests
Two mines were placed on the earth 11’ in front of the radar
in order to see whether a
typical plastic anti-personnel mine would have a significant detection
level. One of the
mines (the green one) was filled with silicone explosive stimulant
and the other was
empty. Here are the two radar images that were generated:

Radar detail
The radar device is physically compact and light as it is intended
for use by an individual.
The system is based on an eighteen element phased array, nine
transmit and nine receive elements. These antennae may be triggered
and the receive antenna digitized in any order to synthesize a beam.
A next-generation radar, has recently been developed that contains
34 antennas, 17 transmit and 17 receive, that operate at 3-5 GHz.
This higher operating frequency will allow higher cross range resolution
and the higher power transmitters and the array gain of the larger
receive array will permit operation at greater ranges.

methods available.
