Passive microwave camera

Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002
A novel microwave imaging technique that is completely passive and has the ability to image objects and scenes that are obscured by smoke, fog, clouds, building materials, and opaque barriers has been developed. The system employs a electrooptic approach to reduce system complexity and cost by orders of magnitude over competing real-time high ...
