pseudo-random code fuzes anti-jamming noise amplitude modulation signal to jamming ratio
The anti-noise amplitude modulation(AM) spot jamming performance of pseudo-random code phase modulation fuze,pseudo-random code phase modulation and pulse amplitude modulation(PAM) combined fuze,and pseudo-random code phase modulation and pseudo-random pulse position modulation(PPM) combined fuze is researched based on the criterion of signal to jamming ratio(SJR) gain.Their SJR and overall SJR gain are reduced according to the same receiver model,and the influence of psuedo-random code period and Doppler frequency on the overall SJR gain of the receiver is analyzed.The results show that these three pseudo-random code fuzes have strong performance of anti-noise AM jamming.The anti-noise AM jamming ability of the pseudo-random code phase modulation and PAM combined fuze and the pseudo-random code phase modulation and pseudo-random PPM combined fuze is stronger than the pseudo-random code phase modulation fuze.
