Random pulse position modulation (RPPM) signal not only has good resolution of distance and velocity, but also has low probability of interception and strong properties of eccm.
随机脉位调制信号不仅具有良好的距离和速度分辨力，而且具有较低的被截获概率和较高的抗干扰性能。

The fundamental principle of the series-parallel msequence is introduced in detail. The circuit prototype of a RPPM generator with the series parallel msequence is also considered.
详细阐述了串-并m-序列原理，并给出利用串-并m-序列产生随机脉位序列的电路实现方案。

From the point of view of the modulation of RPPM, chaotic signal with stochastic characteristics is introduced as its modulation, which has the good performance just like the random signal.
