Optimum design of jamming reconnaissance receiver

This paper presents a channelized jamming reconnaissance receiver, and analyzed false response, amplitude response and temperature drift, which influence the performance of channelized receiver. For the sake of interchangeableness, we divided the receiver into RF assembly and IF assembly, then compensated each assembly independently and estimated system error. At last, we tested the receiver under assemblies (spare parts) interchanged situations at different temperatures. The results show that both absolute and relative accuracy reach ± 2 dB. The purpose of cutting down spare parts and improving maintainability, supportability, reliability has been achieved.
