摘　　要：结合SODERN公司新的地球红外辐射模型,对工作在倾斜轨道上的摆动扫描式红外地球敏感器由于地球红外辐射波动造成的姿态测量误差进行了分析,并对其不同季节时的误差进行了数学仿真,最后得出了不同季节的姿态测量误差。结果表明地球的红外辐射波动对俯仰和滚动姿态测量造成的误差最大值分别为0.16°和0.06°。Based on the SODERN＇ s new infrared earth radiance model, the attitude measuring error caused by the earth radiance fluctuation of swing-scanning infrared earth sensors working on the inclined orbit is analyzed. By means of the mathematic simulation, the earth radiance errors of swing-scanning infrared earth sensors in different seasons are obtained. The results show the maximum values of pitch error and roll error caused by the earth radiance fluctuation are 0. 16° and 0. 06° ,respectively.
