| 摘 要： | 该文在介绍伪码调相与伪随机脉冲位置调制（PPM）复合引信工作原理的基础上，推导了在多普勒频率影响下接收机的总调制制度增益。对推导结果的分析和计算机仿真表明：随多普勒频率的增大，伪码序列周期越大或高频脉冲宽度越宽，其抗噪声性能下降越迅速，对其伪码序列周期、高频脉冲宽度和引信工作频率的设计，能够保证该体制引信良好的抗噪声性能。

| Abstract: | The principle of pseudo-random code phase modulation combined with pulse position modulation(PPM) fuze is investigated briefly.The overall signal to noise ratio(SNR) gain of the whole procedure after correlation detection concerning Doppler frequency is deduced.The analysis and simulation demonstrate that its anti-noise performance becomes weaker rapidly along with the Doppler frequency getting greater if the period of pseudo-random code becomes longer,or the pulse width gets wider.The strong performance of... |
