研究了降雨引起的衰减与去极化效应，根据ITU-R提出的雨衰减预报模型，计算了我国某些城市的地空雨衰减量。将离散雨介质视为一随机系统，利用系统辨识的方法，利用系统辨识的方法，结合某市实验数据得到了一个去极化分辨率的序列模型。

The effects of attenuation and depolarization induced by rain in the ka waveband are discussed. according to the prediction model of rain attenuation put forward by itu-r,the rain attenuation quantity on satellite links was calculated in the 35 ghz frequency in several typical cities in china. the discrete rain medium was taken as a random system.a serial model for computing depolarization discrimination was given by using the system identification method with proportion experiment data in china.the calculated results show that this method is effective and straightforward.
