Abstract

A remote minefield detection system (REMIDS) developed as part of the U.S. Army's Standoff Minefield System Research Program is presented. This helicopter-mounted system based on an active/passive line scanner, real-time processing, and display and navigational equipment obtains image data in three principal coregistered channels via line scanning. Two channels provide near-IR linear polarization reflectance vector information while the third channel provides passive thermal information. Numerous flight tests showed that the REMIDS system is capable of detecting mines during both day and night flight. Polarization is confirmed to be are a good discriminator between man-made and natural objects. Active polarization and reflectance information proved to be superior to thermal data in several natural scenarios including arid regions, overcast conditions, and diurnal thermal crossover periods.
