摘　　要：指出IGSO卫星轨道及姿态运动特点使得地敏探头会扫描经过两极区域,通过国外案例介绍说明分析工作的必要性。简要介绍摆动扫描式红外地球敏感器的复合视场及工作原理,重点分析地敏受两极地区红外辐射波动影响,说明地敏输出姿态角误差成因,建立基于STK软件的仿真工程,对地敏探头受扰情况进行仿真分析。提出解决地敏受两极红外辐射干扰问题的处理措施,利用仿真预报的受扰时段进行探头干扰保护,确保地敏输出姿态角正常。The attitude and orbit motion law of IGSO satellite indicates the field-of-view（ FOV） of earth sensor across both poles every orbit period,it＇s necessary to analysis the effects of infrared radiance fluctuation on earth sensor. This paper summarizes the measurement principle of swing-scanning infrared earth sensor,and explains the formation of attitude errors induced by infrared radiance variation. A STK-based project is designed to simulate and analysis the interference of earth sensor bolometer detectors. A solution for the problem is presented to protect the detector by forecasting the disturbed period of time and ensure normal attitude output of earth sensor.
