The purpose of autofocusing is to remove the radial motion effect of the target from radar echoes, and only reserve the stepped frequency effect which is the basis of synthetic HRR capability.

自聚焦的目的是从雷达回波中消除目标径向运动的影响，只保留步进频率的影响，而后者是合成hrr能力的基础。

Using this method we can reserve low computational complexity and the high performance of motion detection.

采用这种方法既能保持低的计算量，同时又具有较高的运动矢量检测性能。
