| 摘 要： | 为了使微波散射计测得的海面后向散射具有足够的精度，必须考虑大气对微波衰减的影响。大气对微波的衰减可以用微波射计来测定。本文将估算晴空、云和降雨天气下的衰减系，讨论计算海面发射率及用微波辐射计剩余亮温估算散射计工作频率下大气衰减的方法。 |

| Abstract: | To measure the backscatter of scatterometer from the ocean with enugh accuracy, the effect of atmospheric attenuation over the sea must be considered. The attenuation can be determined by using microwave radiometer. The. attenuation coefficients under clear sky,cloudy and rainfall conditions have been estimated. The methds to estimate the sea surface emission and atmospheric attenuatin with the excess brightness temperature of microwave radiometer at the scatterometer frequency are discussed. |
| Keywords: | Atmospheric attenuation scatterometer radiometer |
