Abstract

The paper presents the concept of the algorithm to detect and estimate motion parameters of ground slow moving targets. Detection algorithm based on Sigma-Delta antenna with two spatial channels STAP processing. Motion parameters were estimated using novel Non Iterative Map-Drift (NIMD) technique, typically dedicated as an autofocus technique for earth imaging in SAR technique. The main goal of this paper was to extend and test NIMD technique as an algorithm for ground moving targets detected with two channels (sigma/delta) antenna.
