Passive target signature measurements were performed at 220 GHz and 95 GHz. Test results show target detection is possible even with very warm sky temperatures. A 220 GHz94 GHz sensor was used to detect a metallic vehicle at a range of 300 meters during the summer. Using a raster scan format, scans were made above, through and below the target. The scene thus viewed included trees and grass. Measurements were also made of the overhead sky and calibrated hot and cold radiometer loads.
