Performance Analysis of Anti Noise FM Jamming of Pseudo-random Code Binary Phase Modulation Fuze Based on Doppler Effect

Performance analysis of the pseudo-random code binary phase modulated (PRC-BPM) fuze is analyzed in this thesis. Firstly, its principle is introduced in brief. On this basis, the signal to jamming ratio (SJR) gain of its receiver in noise FM jamming is deduced in detail with Doppler frequency. Then, the effect of Doppler frequency, pseudo-random code width, the of period pseudo-random code serial and aiming frequency deviation on its performance of anti noise FM jamming is analyzed. The results indicate that the PRC-BPM fuze has better performance of anti noise FM jamming.
