The invention provides a drift angle compensation method for pitching maneuver of a swing-broom imaging satellite. The drift angle compensation method comprises the following steps: step 1, designing a track of swing-broom maneuver; 2, solving a drift angle according to an image motion speed model on a focal plane; 3, designing a pitching maneuvering compensation drift angle track; 4, determining an initial value of a drift angle compensation track parameter; and 5, adjusting drift angle compensation track parameters by using an iteration method. According to the method, main causes of the drift angle in load swing-scan imaging are analyzed, and the ground image motion speed caused by the satellite moving along an orbit is counteracted by utilizing the angular speed of a satellite platform in the pitching direction, so that compensation of the drift angle of the swing-scan imaging satellite is realized, and the imaging quality of the wide swing-scan imaging satellite is improved.

    本发明提出一种摆扫成像卫星俯仰机动的偏流角补偿方法,包括步骤为:步骤一:设计摆扫机动的轨迹;步骤二:根据焦面上的像移速度模型求解偏流角;步骤三:设计俯仰机动补偿偏流角轨迹;步骤四:确定偏流角补偿轨迹参数初值;步骤五:用迭代法调整偏流角补偿轨迹参数。该方法通过对载荷摆扫成像中偏流角的主要成因分析,利用卫星平台俯仰方向的角速度,对卫星沿轨道运动引起的地面像移速度进行抵消,从而实现对摆扫成像卫星偏流角的补偿,提高宽幅摆扫成像卫星的成像质量。
