Performance Analysis Concerning Antinoise for Several Pseudo-random Code Fuzes
Jibin Liu, Cpla Air · Acta Armamentarii · 2005
The principle of three kinds of pseudo-random code fuzes, viz. thepseudo-random code phase modulation fuze, the pseudo-random code phase modulation and pulse amplitude modulation combined fuze,and the pseudo-random code phase modulation and pseudo-random pulse position modulation combined fuze-were introduced in brief. On this basis, their SNR gains in signal processing from the backward of band pass filter to the forward of the correlation detection, and the overall SNR gains of the whole procedure after correlation detection were deduced in detail. The results show that the latter two kinds of fuzes have the same performance concerning antinoise and are stronger than that of the pseudo-random code phase modulation fuze.
