脉冲信号在导引头测试中的检测方法研究

Study on the testing of pulse in an automatic test system of radar seeker

在现代雷达导引头中,种类繁多的脉冲信号是反映其工作性能的重要参数,成为导引头测试技术研究中的重点和难点。根据某型导引头测试需求,对脉冲计数和脉冲采集等2种方式在本测试系统中的应用进行了研究,主要包括信号调理电路、触发电路的设计,以及对应PCI板卡的上位机程序设计。经该型导引头的实际应用验证,给出的方法能够满足不同脉冲的测试需要。

Because of the importance in reflecting the performance of a radar seeker,the processing method of pulse becomes one of the most important parts in our research on an automatic test system.In considerations of the request for testing a radar seeker,two methods are used in our test system：.counting and collecting.The design of electric circuit for processing or triggering are introduced in this paper,so do the programs for the PCI cards.These two methods have been used in our testing system and proved effective by running for a long time.
