Successful Application of Low Loss, Over-Moded WR-187 Waveguide to the ASDE-3 Radar

摘要

Overmoded WR-187 waveguide has been incorporated into the short-range ASDE-3 system to provide a low-loss interconnection between the antenna and the transmitter/receiver. WR-62 to WR-187 transitions and WR-187 mode suppressors were developed specifically for this short-range radar application to provide low loss transmission of 0.01 dB per ft. The 36-nanosecond, 160-dB dynamic range ASDE-3 system is operating without resonance effects down to the required minimum radar range of 500 ft. This report presents pertinent technical detail and briefly describes the testing process. (Author)
