Performance analysis of global navigation satellite system anti-jamming optimal receivers and correlation receivers
摘要
Abstract
In order to reduce the hardware realization difficulty,the GNSS (global navigation satellite system) sole antenna anti-jamming correlation receivers were studied in partial-band interferences circumvent.Their frequency responses,SINR (signal-to-interference-noise ratio) losses and correlation output functions were analyzed.It is shown that the SINR losses of anti-jamming optimal receivers and correlation receivers will increase with the bandwidth and power increase of interferences.The SINR losses will decrease with the bandwidth increase of noise and the frequency difference will increase between interferences and signals.Moreover,the match and correlation output main lobes will be depressed and the side lobes will be raised by jammers so as to affect the acquisition,track and multipath mitigation performance of anti-jamming receivers.Analysis results will provide the design basis for the GNSS anti-jamming receivers.关键词
