THE MODEL OF DIGITAL TEMPORAL AND SPATIAL ANTI-JAMMING SYSTEM FOR GPS RECEIVERS
GPS signal is easily influenced by interference. An adaptive antenna array combining with temporal anti-jamming processing can be used to mitigate interference and improve GPS signal acquisition. This paper addresses an all-digital temporal and spatial anti-jamming implementation scheme based on adaptive antenna array. Temporal adaptive filtering techniques can effectively suppress narrowband interference, however, the presence of an antenna array allows the receiver to operate in spatial domain in addition to time domain, which can improve the performance of GPS receiver with broadband interference.
