Passive Millimeter-Wave Target Detection Radar

Passive millimeter-wave target detection radar operates entirely passively by receiving the radiometric brightness temperatures of both the target and the background, and detects targets by comparing the differences in these brightness temperatures. It offers advantages such as all-weather operation, excellent stealth, and independence from signals emitted by non-cooperative targets, while simultaneously delivering robust target detection performance and exceptional survivability.
