雷达视频信号模拟器的设计

论述了雷达视频信号模拟器的设计思想及用计算机模拟目标和杂波的方法。模拟器采用硬件结合的方法实现，对于点目标采用Ｓｗｅｒｌｉｎｇ模型，对于杂波模型注意考虑各杂波单元间的相关性，由微机计算出描述各种环境模型的数据并将该数据加载至硬件电路。在定量信号来到时，由数字信号处理芯片完成所需的实时运算，由信号产生电路产生包含目标和杂波的视频信号。

Design of Radar Video Signal Simulator

Methods of designing radar video signal simulator and simulating radar targets and clutter were discussed The simulator was implemented by mixed means of software and hardware Swerling model was adopted for dot target and the correlation between clutter units was considered for clutter model The data for different environment models was calculated by PC and was downloaded to hardware circuit When the timer signal came,the real time calculating was achieved by DSP and the video signal consisted of the target and clutter was generated by signal generation circuit The design has been certificated by conjunction of the simulator and the radar signal processor
