摘    要:简单介绍了伪码调相引信,伪码调相与脉冲幅度调制(PAM)复合引信,伪码调相与(伪)随机脉冲位置调制(PPM)复合引信的工作原理。推导出它们从带通滤波后至相关检测前这一过程中信号处理方面的信噪比增益,以及至相关检测后整个过程中信号处理方面的总信噪比增益。结果表明后两种引信具有相同的抗噪声性能,且均强于伪码调相引信。

关 键 词:通信技术  伪码  抗噪声  信噪比  相关检测  引信

Abstract: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.
Keywords:communication technique  pseudo-random code  antinoise  signal-to-noise ratio  correlation detection  fuze
