这时需要分距离单元进行时频分析，得到距离-瞬时多普勒图像。
In this case, time frequency analysis must be performed for every range cell to obtain range instantaneous Doppler (RID) image.
利用瞬时多普勒频率与波束斜视角的对应关系构造出一种具有闭合解的距离弯曲因子。
A close-form range curvature factor is constructed through the correspondence of the instant Doppler frequency to the squint angles.
