摘要
为了满足某型雷达系统性能检测的要求，基于AD9910芯片设计了一种高分辨力、宽频带、快速频率转换的高性能雷达信号模拟器。系统采用分布式控制原理，上位机由嵌入式PC104工控机组成，下位机由FPGA对DDS进行控制在12.5～16 GHz范围内输出雷达回波信号。实验测试结果表明，该雷达信号模拟器输出波形稳定，各项设计指标均达到系统设计要求。
In order to meet performance test requirements of a certain radar system,a high resolution,wide frequency band,fast frequency conversion of high performance radar signal simulator based on the AD9910 chip was designed. The princi？ple of division control is used for the system. The host computer is composed of the embedded PC104 IPC. The lower computer controlled by the FPGA on the DDS outputs radar echo signals in the range of 12.5~16 GHz. The experimental results show that the output waveform of the radar signal simulator is stable,and each design index can satisfy the design requirements of the system.
