The technique of moving target detection is more important in military affairs such as surveillance. And in last few years, people pay more attention to the distributed SAR systems. Both the Along-Track Interferometry (ATI) and Displaced Phase Center Antenna (DPCA) techniques can estimate the position and radial velocity of moving target; however they are used in different situation. The paper do specialized treatise to this. In the paper we compare the detection performance of slow ground moving target using the ATI and DPCA technique for the new model of distributed space-borne SAR in detail. And some typical computer simulation results are presented which illustrate the problem convincingly.
