摘要

本文提出一种适用于近场转台成像的修正广义相干处理法，即对每一小转角内的距离－多普勒成像结果进行近场修正，从而实现近场大转角成像的方法。与球面反投影法相比，该方法计算量少，成像质量好。

Abstract

A modified extended coherent processing（MECP） method is proposed in this paper to reconstruct near-field microwave images of conducting objects which are mounted on a rotating platform. In the method

the results of range-Doppler （R-D） imaging in all subintervals of the total rotating angle are corrected for the near-field case and then coherently added together.The simulation results show that the MECP method not only needs less calculation but also is more efficient than the SBP algorithm.
