文中拟合得到了由降雨的雷达体反射率反演雨衰减率的公式,适用频率1~100 GHz,并且给出了降雨存在时的雷达方程、最大作用距离以及雷达接收信号信噪比与信杂比的变化。文中的结果对降雨存在时雷达的目标检测具有指导意义。

A new model is developed for the computation of rain specific attenuation from rain volume reflectivity,for frequencies from 1 GHz to 100 GHz,and the radar equation,maximum range and signal-to-noise ratio and signal-to-clutter ratio in rain have also been analyzed herein. These results have practical meaning in radar target detecting during raining.
