AT-InSAR (Along Track InSAR) can be used to detect slow-moving target by the along track component of baseline in the distribute satellites SAR system,. The detecting performance is influenced by the noise and clutter greatly for slow moving target. In this paper, the different influence of the noise and clutter on the detecting performance is analyzed. By simulating different background clutter and noise, the performances of those methods are discussed in detail, and the adaptive-threshold method can improve the detection performance greatly. On the other hand, the detecting performances can be improved by multi-channel integration technique.
