Excerpt
Excerpt: In order to detect buried land mines in clutter, Planning Systems Incorporated has developed a Ground Penetrating Synthetic Aperture Radar (GPSAR) system for the U.S. Army CECOM Night Vision and Electronic Sensors Directorate. The GPSAR system is a wide-band stepped-frequency radar operating over frequencies from 500 MHz to 4 GHz. Our GPSAR uses multiple transmit and receive antennas to acquire data at 58 across-track locations separated by 1.47 inches. Along-track data sampling is provided by the forward motion of the system. Multiple radar channels and high-speed radio frequency switching are used to accelerate the data acquisition process and increase the system’s maximum speed of advance. Synthetic aperture, near-field beamforming tech- niques are used to reduce clutter and enhance the signature of buried objects. While the system is designed for mine detection it is capable of locating deeper objects such as buried utility pipes. Tests conducted in December 2001 at U.S. Army facilities indicate that the system can detect both metallic and plastic landmines at depths up to 6 inches. A description of the PSI GPSAR system and test results are presented. Keywords: Ground Penetrating Radar, Synthetic Aperture, Mine Detection.
