摘要：

This paper presents new algorithms for moving target detection and velocity estimation for multi-channel SAR (Synthtic Aperture Radar) system. The algorithms are derived as the extensions of conventional DPCA (Displaced Phase Center Antenna) and ATI (Along Track Interferometry) to the multi-channel case. The proposed multi-channel DPCA based on orthogonal projection completely suppresses the static clutter even with the presense of the azimuth ambiguity. The multi-channel ATI utilizes the phase differences of all the pairs of the channels to estimate the target radial velocity. The combination of the two, which we call multi-channel DPCA-ATI, is also proposed as the more robust velocity estimation method.
