| 摘 要： | 通过把测试信号输入功率换算到雷达天线喷口处接收功率的计算，由雷达气象方程可计算出其雷达反射率z值，和经雷达接收功率定标后，此测试输入功率在雷达正常观测模式显示的雷达反射率z值相比较，以检验天气雷达接收功率标定的误差是否满足技术要求。

| Abstract: | By calculation of the equivalent received power of testing signal input power at the radar antenna feed, the radar reflectivity Z(dBz) value of testing signal input power can be calculated by the meteorological radar equation.By comparing with the displayed Z value of the testing signal input power after the calibration of the radar received power on the radar normally observation model,it is examined whether the error of the calibration of the weather radar received power meet the technical demands. |
