当舰速造成动静目标回波频谱太近时，须改变其相参信号实现补偿。

The close distance between moving and quiescent target spectrum caused by the moving carrier, Compensation was realized through the coherence signal parameter was changed.

图象中的动目标可以通过雷达回波的频谱特性进行分析、检测和分离，并能将动目标频谱移动到原点。

In SAR image moving targets can be analysised, detected and detached by spectrum characteristics of the radar echoes, and the spectrum of moving tar-gets can be shifted to the origin.

本文通过所建立的采样比率模型对多目标的距离闪烁效应进行了理论分析，并从回波频谱畸变的角度解释了其物理本质。

In this paper, the range glint is analyzed in theory through the model of sample ratio established, and then its physical essence is also expatiated using echo spectrum aberration.
