Abstract：Performance of anti-noise for the pseudo-random code phase modulation and pulse amplitude modulation combined fuze based on Doppler effect are discussed in this thesis. Firstly, the principle of them are introduced briefly. Secondly, on this basis, the overall SNR gains of the whole procedure after correlation detection are deduced in detail. Their performance of anti-noise is analyzed, which is affected by Doppler frequency, the period of pseudo-random code and the pulse width of code-element .The results show that the performance of anti-noise for the latter fuze is better than that of the pseudo-random code phase modulation fuze. And the good performance of anti-noise can be guaranteed by designing on their parameters.
