摘要
介绍３种计算Ｋｕ波段雨衰的数学模型，并且讨论其雨衰特性。根据３种数学模型预测各种情况下的雨衰值，并同实测数据进行比较。最后讨论我国雨区分布情况及Ｋｕ波段雨衰裕度。
hree mathematic models of estimating rain attenuation of the Ku band are described and the characteristics of this band rain attenuation are discussed.According to these models.the values of the rain attenuation are estimated at a variety of cases and compared with the measured data.Finally,the rain area distribution in China and the margin of the Ku band rain attenuation are discussed.
