摘　　要：对月定标具有不依赖地面定标场、不受天气影响、定标效率高等优势,但需要解决对月姿态控制及成像参数匹配性设计问题。文章针对光学遥感卫星推扫成像,提出一种姿态机动补偿方法,用于解决星载相机对月成像过程中积分时间与推扫速度失配的问题,并以一颗太阳同步轨道卫星作为分析对象,研究了卫星对月成像时的补偿角速度,经过对姿态机动补偿过程进行仿真分析,结果表明:使用该方法可以使相机推扫速度与积分时间匹配,达到正常对月成像的目的。On-orbit lunar calibration takes advantage of not relying on calibration field or weather and is more effective.But attitude control and imaging parameters matching design problem should be solved.An attitude maneuver compensation method is proposed for the optical remote sensing satellite to solve the mismatch of integral time and scanning rate when the TDICCD camera carries out the lunar imaging task.And a sun-synchronous orbit remote sensing satellite is taken as an example for analysis.The satellite＇s compensation angular velocity which enables the regular imaging is calculated and verified by the simulation software.The simulation method shows that the method proposed in this article can be used to match integral time and scanning rate and obtain valid lunar images.
