摘　　要：多普勒天气雷达发射系统测试时,一般需要天气雷达停止工作,断开部分待测试组件之间的电连接,因此测试时可能出现异常指标,导致测试时长不可控。针对该情况,文章按照天气雷达正常工作状态,对发射系统各个待测试组件进行连接。通过测量各低压待测试组件输出采样信号,或者通过高压测试工装转接后,再测量高压待测试组件的输出高压信号,从而实现在多普勒天气雷达正常工作的情况下对发射系统开展技术测试的目标。When testing the Doppler weather radar transmitter system,it is generally required to stop the operation of weather radar and make the electrical connection between partial components to be tested disconnected.Therefore,the anomaly indexes are possible to occur during testing,causing the duration of test to be uncontrollable.Against this situation,in the paper,all the components to be tested in the transmitter system are connected under the condition that the weather radar operates normally.By measuring the output sampling signal of all low-voltage components to be tested or by making the high-voltage test tooling switched over first and then measuring the output high voltage signal of high-voltage components to be tested,it is possible to realize the objective of conducting technical testing for the transmitter system during normal operation of the Doppler weather radar.
