某电子对抗系统干扰反应时间指标测试方法的改进

Improvement on Testing Method for Interference Response Time of Certain Type Electronic Countermeasures System

为解决某电子对抗系统验收测试过程中,原测试方法对测试设备要求较高、测试时间较长等问题,提出一种改进方法。采用普通示波器来替代高速示波器,射频前端增加检波器,对射频信号进行检波,干扰反应时间为信号源输出射频信号和干扰机输出干扰信号的检波信号由低到高变化的时间差值,降低了对测试设备的要求、缩短了测试时间。分析和试验验证结果表明:在不影响测试准确性的情况下,该改进方法是有效可行的。

In order to solve the problems of the original test method in the acceptance test of an electronic countermeasure system,such as high requirements for test equipment and long test time,an improved method is proposed.A common oscilloscope is used to replace a high-speed oscilloscope,a detector is added at the front end of the radio frequency to detect the radio frequency signal,and the interference reaction time is the time difference value of the change of the detection signal of the radio frequency signal output by the signal source and the interference signal output by the jammer from low to high,so that the requirements on the test equipment are reduced,and the test time is shortened.The analysis and experimental results show that the improved method is effective and feasible without affecting the accuracy of the test.
