视频SAR作为一种新型微波遥感体制，可用于对热点区域动态目标的持续监视。提出一种基于大角度聚束模式的视频SAR实现方法，分析视频SAR回波数据分割机理以及基于敏捷SAR卫星视频成像模式的姿态机动策略，并通过偏航补偿实现不同视频帧成像区域的无旋转控制，最终给出三轴期望姿态与姿态角速度。通过数学仿真验证上述姿态机动策略的有效性。
As a new microwave remote sensing mode, video SAR provides a continuous surveillance over a region of interest. An implementation method of video SAR based on spotlight SAR imaging mode is proposed in this study. The segmentation method of SAR raw data and the attitude maneuver strategy for video SAR are also discussed. Rotation between consecutive frames is avoided through yaw compensation, and Euler angles and angular rates are obtained based on theoretical analysis. Finally the simulation and numeric experiments verify the feasibility of the method and strategy.
