多波段SAR是SAR技术发展的一个重要方向，不同波段SAR图像之间的精确配准是综合利用多波段SAR 图像信息的前提。运动测量系统的误差(即残余运动)是影响图像配准的重要误差来源之一。针对这一问题，该文研究了残余运动误差对SAR成像几何定位的影响，在此基础上定量分析了残余运动与机载多波段SAR图像配准精度之间的关系，并通过仿真验证了理论分析的正确性。

Multiband SAR is an important trend in SAR technology. Accurate registration among different band SAR images is a prerequisite for the comprehensive utilization of the information of multiband SAR images. Errors in the motion measurement system (i.e., residual motion) are major error sources affecting image registration. To solve this problem, the effect of residual motion error on SAR imaging geometry positioning is investigated. The relation between residual motion and image registration accuracy of airborne multiband SAR is analyzed quantitatively. The results of the theoretical analysis are verified by simulation experiments.
