具有快速姿态调节能力的敏捷卫星，可灵活、快速地机动到感兴趣区域并进行成像，大大提高卫星观察的时效性，并扩大观察范围。目前敏捷卫星大多采用星下点推扫成像或沿平行于卫星飞行方向推扫成像的方式，研究机动成像过程中，分析时间延迟积分电荷耦合器件(TDICCD)成像参数及图像质量的变化情况，对成像过程中的误差影响进行了分析，给出了关键参数变化情况的仿真结果，提出实现机动成像卫星的控制措施建议。

Agile satellite can point to any interested place very deftly and fast, improving observe range and time efficiency of mission greatly. Most agile satellite take pictures either along satellite track or parallel with satellite track. Imaging parameter and imaging quality of change time delay and integration charge coupled devices (TDICCD) during dynamic imaging process are analysed, error effects on image quality are given, and simulation result of main parameters change is acquired, in the end satellite control method is proposed.
