无源定位系统的基本原理是通过多个站协同工作，在中心站分析各站捕获信号的时间差来对目标进行具体定位，精确的定位对中心站与边站之间传送脉冲信号的微波传输系统提出了很高的要求。文中针对该问题，在分析多基地无源雷达视频脉冲传输系统的原理及系统的门限效应的基础上，通过系统仿真，对接收端脉冲的前沿抖动量等关键指标进行了测量及分析，探讨和研究了不同视频脉冲调制方式和信道构成方式对多基地无源雷达视频脉冲传输系统的性能影响。

The passive position system carries on the localization by analyzing the signal time-of-arrive between each station. Exact passive position requests the transmission microwave system between central station and sub-station to be extremely precise. In this paper,we first analyze the principle of the multistatic passive radar video pulse transmission system and the threshold effect theory, then through the system simulation, some key parameter such as leading-edge jitter is deeply studied to investigate the influence of performance by various of video pulse modulation and channel constitution mode.
