| 摘 要： | 分析得出地球扁率和红外辐射是扫描式红外地平仪测量误差的主要原因。针对地球扁率，基于方位角的确定，分别给出了滚动角和俯仰角的测量误差模型。在地球红外辐射方面，给出了确定地平仪扫人、扫出点位置的方法，进而给出地球红外辐射误差的计算方法。最后，通过算例，给出了有关仿真结果，对方法的有效性进行了验证。

| Abstract: | The reason of attitude correction of scanning infrared horizon sensor is presented by reason of Earth's oblateness and infrared radiation.In allusion to Earth's oblateness,roll/pitch models of attitude correction based on the azimuths are given.We also provide the method of how to determine the space to Earth and Earth to space crossing point.Furthermore,the algorithm of attitude correction of infrared radiation is present.A numerical example is given and shows that the algorithm is valid. |
