TT&C遥测误码率测试方法的改进

Improvement of BER Test Method in TT&C Telemetry System

为了全面检验设备工作性能,提供更多的调试依据,通过误码率分析,指出PSK调制与误码率性能的关系,讨论了TT&C解调终端的误码率测试方法存在的不足,根据现有条件提出了一种TT&C遥测误码率测试的改进方法。该方法对检验中频接收机的工作性能及调试有着指导意义,结束了遥测解调性能只能定性、粗略检查的现状,为主战设备选取提供了理论依据。

In order to test the overall performance of equipment and provide more debugging basis, the relationship between PSK modulation and BER is introduced, and the shortcomings of BER test in TT＆C modulation terminal are discussed. Then an improved method to test BER in TT＆C is proposed according to current conditions. This method provides the reference for testing and debugging IF receiver, and ends the condition that only performance determination and simple checking can be executed in TT＆C modulation. It provides the theoretical guidance for main equipment selecting.
