摘要
多普勒频移模拟器是多普勒导航雷达自动测试设备最重要的测试资源之一。本文介绍了一种多普勒频移模拟器的实现方法。电路为数模混合的形式,通过使用嵌入式控制系统、对分立元件与模拟集成电路的合理运用,使电路性能稳定可靠。
Doppler frequency-shift simulator is one of the most important test resources of Doppler navigation radar automatic test system （ATS）. One design of Doppler frequency-shift simulator is introduced here. Digital and analog hybrid circuit is adopted. Because of the employment of embedded control system, appropriate use of discrete components and analog IC,and effective anti-interference measures, the simulator can operate stably.
