摘要
现代雷达功能越来越复杂，对雷达系统的设计、调试和测试也变得越来越困难。为适应现代雷达设计、调试和测试而发展的雷达系统模拟器技术是数字模拟器技术与雷达相结合的产物。雷达信号模拟器具有经济、灵活等特点，可以解决外场试验成本高、受天气影响等问题，满足雷达系统研发的需要，因此研制各种各样的雷达信号模拟器对于现代雷达的研制、生产都具有重要意义。
本文以机载相控阵雷达视频信号模拟器的研制为背景，以实现和差通道的目标和杂波模拟为重点，对该系统的雷达时序产生和系统的视频输出等问题的设计和实现进行了较深入的研究。

（1） 雷达回波信号回波模型（着重对目标，杂波）进行了分析，并介绍了模拟器视频部分的实现方案。
（2） 根据系统的总体方案中的雷达接口部分及视频输出部分的要求，完成了雷达模拟源及D/A板的设计。
（3） 完成了机载相控阵雷达模拟器视频分机雷达模拟源及D/A板的PCB制作，调试工作。
（4） 完成了雷达模拟源及D/A板的相关程序。
（5） 针对国家“九.五”某预研项目，与课题组成员共同设计并实现了一套“机载相控阵雷达视频信号模拟器”系统，测试结果表明该系统达到了系统设计的主要技术要求，可以提供满足某机载相控阵雷达地面调试要求的雷达信号。
