速高比为飞行器飞行高度与飞行速度比值
本文研究了卫星摄影系统象移补偿速高比计算。
A calculating method of velocity-height ratio for image-moving compensation of a satellite photograph system is presented.
但是，从卫星上拍摄地面照片时，如果把速高比中的速度取为地面相对于卫星的速度，则会导出谬误。
However, when the scene on the ground is photographed from a satellite, if the velocity was taken as one of the ground relative to the satellite, then the great error would be made.
结果表明，随着积分级数的增加，像移对相机成像质量的影响越来越大，尤其表现为偏流角及速高比的变化。
The effects of the image motion caused by them on the image quality for different integral numbers are calculated and simulated for a given orbit and camera.
