| 摘 要： | 首先建立用于微波被动遥感的一维综合孔径微波辐射计的理想信道仿真模型,在此基础上通过分析单元天线方向图的不一致、信道的幅度相位不平衡与信道间串扰对反演亮温的影响来对综合孔径微波辐射计的天线和信道部分的误差进行分析,并建立系统仿真模型.建立的仿真模型所反演的目标亮温能够更真实地反映被观测目标的实际情况.

| Abstract: | A idear multi-channel signal model for 1-D synthetic aperture radiometer was firstly introduced, and then based on this model, the variations of antenna patterns, the imbalance of anplitude and phase between channels, and the multual-coupling between channels were incorperated to simulate the affection to the retrieved brightness temperatures. The temperature of objects were retrieved by using the simulation model are good agreement with that true one. |

| Keywords: | synthetic aperture radiometer antenna pattern channel imbalance mutual-coupling |
