摘要

星载SAR平台的聚束模式往往需要将其有效载荷指向地面上的固定目标，这意味着卫星姿态必须在固定的时间跨度内遵循特定的轨迹。本文推导了姿态角、角速度和角加速度。为此，提出了一种带前馈的PD控制律。通过具有外部干扰和不确定模型的数值仿真验证了该方法的有效性。

The attitude tracking maneuvers of spaceborne spotlight SAR

The spotlight mode of spaceborne SAR platforms often have to point its payload to immobile target on the ground which means the satellite attitude have to follow a specific trajectory in a fixed time span. In this paper, the attitude angle, angular velocities and angular accelerate are derived. A PD control law with feedforward is developed to achieve the purpose. The approach is verified using numerical simulation with external disturbance and uncertain model.
