Analysis of the Concept of Forming 3D Moving Target Image

The concept of forming 3-dimensional moving target image in air-born SAR is analyzed in this paper.First,the shortcoming of using conventional processing method is explained.Then,"smeared spot" actually contains useful target information is pointed out.A system block diagram for extracting useful information is presented.Finally,the description of obtained target 3-dimensional image is emphasized,and some pictures are given.But the current method suffers from large computation load.So further research on improvement is needed.
