Performance Analysis of Anti Aiming Noise AM Jamming for Pseudo-random Code Phase Modulation and PAM Combined Fuze

The performance of anti aiming noise AM jamming for the pseudo-random code phase modulation and PAM combined fuze is discussed in this paper. First, the principle of the combined fuze is introduced briefly, then, the signal to jamming ratio (SJR) and SJR gain of its receiver are deduced in detail when there exists the aiming noise AM jamming. Finally, its performance of anti aiming noise AM jamming is analyzed. The results show that the combined fuze not only has stronger performance of anti aiming noise AM jamming, but the performance can be improved further through designing appropriate parameters such as pseudo-random code period, code-element width and high frequency pulse width.
