Interference Excision of GPS Received Signal in Complex Environment
Anti-jamming of GPS receiver is an important problem in navigation war,and this topic has been well researched recently.However,anti-jamming in the complex receiving environment has not been considered in the most of the researches.To solve this problem a cascade antijamming method is proposed in this paper.In this scheme,each channel of the received signal vector is processed by utilizing a method based on STFT,after the signal in each channel passed through the processor,a spatial processing has been employed to,suppress the reserved interferences.The results of simulations show that,it can be seen from the time-frequency spectrum before and after the first step processing that the single-tone and non-stationary interferences have been mitigated,and it demonstrates that the performance of the ideal classic Weiner filter can be achieved in the proposed method.
