针对单星测向定位中干涉仪设备复杂、卫星姿态测量要求高等不足，提出了一种基于多普勒变化率的单星无源定位方法。

Due to the complexity of the interferometers and high requirement of satellite attitude, a method of passive localization based on Doppler rate-of-change of single satellite channel is presented.

首先，简介主SAR卫星与伴随卫星编队所构成干涉测量系统的工作原理，当主SAR卫星施加偏航导引补偿多普勒频移时，为实现波束指向同步，伴随编队需进行构形与姿态的协同控制。

When SAR satellite compensates Doppler Shift with yaw steering, for beam pointing synchronization, formation maintenance and attitude control of concomitant satellite formation should be coordinated.
