使用350GHz 雷达成像系统检测对峙隐匿武器:A prototype active 350 GHz imaging system has been developed for concealed-weapon detection. This prototype uses a
high-performance heterodyne transceiver coupled to a near diffraction limited quasi-optical focusing and scanning
system. The system can be operated at ranges of 2, 5, or 10 meters and obtains full 3-D imagery of personnel in as little
as 10 seconds. The resolution of the system matched or exceeded the design expectations.
