首先给出了伪随机相位调制与脉冲调制 (PPM )信号及PPM伪随机码的产生方法 ,在此基础上介绍了一种新的复合引信———基于伪随机码的相位调制与脉位调制复合引信 ,详细阐述了其实现原理 ,推导了各个阶段的信号形式。最后通过分析复合引信的特性 ,证明复合引信具有优越的综合性能 。

A method of generating pseudo-random PPM signal and PPM pseudo-random code was brought forward. On this basis, a new combined fuze—combined phase modulation and pulse position modulation fuze based on pseudo-random code was introduced.Principle of the combined fuze was illustrated and the formula of signals in each stage was deduced. By analyzing the performance of the combined fuze, it is proved that the combined fuze has its advantageous general performance, and in particular its strong characteristics of ECCM is given.
