  1. After analyzing the theory of mtdi and setting up the model of moving target echoes, the dissertation discusses in detail the effect of moving target doppler center frequency and doppler rate on the conventional sar image. it also analyzes detailedly the range migration of moving target from time field and frequency field and provides migration model in both fields. after that, it divides algorithms of mtdi into several classes, analyzes the influence of signal - to - noise on the detection results and gives the flow chart of moving target imaging processing
