大气对频率为14.59GHz微波散射计信号衰减的计算

A method to correct atmospheric attenuation of microwave scatterometer at 14.59 GHz frequency

本文利用Seasat－A卫星辐射计实测的大气中的水气含量、云中液态水含量及降雨强度等参数计算大气对微波的衰减，从而实现对14．59GHz微波散射计衰减进行补偿之目的。

Based on a detailed discussion on a method to correct atmospheric attenuation of mi-crowave,the paper calculates microwave attenuation by use of Seasat-A satellite radiometermeasurement data, including atmospheric water vapour content, atmospheric liquid watercontent and precipitation rate. The results are to compensation microwave scatterometer at-mospheric attenuation at 14. 59 GHz frequency.
