Jamming effectiveness of noise amplitude modulation signal to pesudo-random code fuze

Pseudo-random code fuze has strong anti-interference ability. The paper studies about the jamming effectiveness of noise amplitude modulation operating on pseudo-random code fuze. Firstly the operating principle of pseudo-random code fuze is introduced. Then we analysis the characteristic of the noise amplitude modulation signal, following that is the study on the pseudo-random code fuze responses at all levels under noise amplitude modulation signal jamming. Studies have shown that the value of pseudo-random code fuze correlator output will decrease linearly as noise power increases when the power of noise amplitude modulation is low, but tends to be constant when the power of noise amplitude modulation arrives at a certain level. So under noise amplitude modulation jamming, higher jamming power doesn't show the best performance, but there is an optimal value of jamming power.
