%X Based on principle of orthogonal projection filtering, it is introduced firstly, the method of AM-FM interference excision using projection filtering in pseudo-random code fuzes is analyzed in detail. Moreover, the method in some cases is simulated. And, the correlator output SNR using projection filtering is deduced in detail. The results show that the method could filter not only FM interference effectively, but also AM-FM interference in pseudo-random code fuzes. Furthermore , the method could improve the output SNR, and could not cause distortion to the desired PN code at the receiver. However, estimation error of interference parameters has significantly effect on the performance of AM-FM interference excision using projection filtering.
