This thesis discusses mainly the hardware design and development of a simulator for airborn phase array radar. The long period of the simulator is implemented by SDRAM MODULES used in Personal Computer, the broadband is implemented by D/A with internal double-data-channel switching architecture, and the control is implemented by a single CPLD.

本文主要探讨了一种机载相控阵雷达回波模拟器的硬件设计和工程实现，采用了PC机内存常用的超大容量高速缓存SDRAM MODULES来实现输出信号的长周期，采用内部具有双路数据分时切换结构的D/A实现输出信号的宽带，采用一片CPLD完成整个系统的时序逻辑控制。
