In order to detect anti-tank mines in noisy backgrounds, we have developed a ground penetrating SAR. The system operates over the frequency band 500 MHz to 1.8 GHZ. Our GPSAR system uses multiple transmit and receive antennas to acquire stepped-frequency data at 26 cross-track focal locations each separated by 1.38 inches. System motion is used to achieve along track data sampling. Multiple radar channels and high-speed radio frequency switching techniques are used to accelerate the data acquisition process, thereby increasing the system scan rate. Synthetic aperture, nearfield beamforming techniques are used to reduce clutter. The system is optimized for mine detection but is also capable of detecting deeper objects. Test against actual miens on US Army mine lanes indicate that the system can detect both plastic and metallic anti tank mines as well as anti-personnel mines. Images and analysis of data from these test are presented.
