分析雷达视频信号模拟器的通用结构，并根据多体制视频信号模拟器的要求，设计出基于模块化的结构灵活、参数可变的信号模拟器。为解决模拟器所需海量存储器与物理实现之间的矛盾，提出一种随机抽取法，利用有限杂波、噪声模拟海量伪独立分布杂波、噪声，收到了较好的效果。
The general structure of radar video signal simulator is analyzed. According to the requirement of multi-system video signal simulator, a signal simulator based on modular structure with flexible parameters and variable parameters is designed. In order to solve the contradiction between the mass memory and the physical implementation required by the simulator, a random extraction method is proposed, which uses the limited clutter and noise to simulate the mass pseudo-independently distributed clutter and noise and receives good results.
