Abstract

Standard SAR-processing methods are based upon the assumption of a scene at rest. If targets are moving, their positions in the SAR-image are translated in azimuth and defocusing may occur. In this paper, some methods for the detection and imaging of moving targets and the estimation of their real positions are discussed, such as monopulse and DPCA. Experimental results are shown on position correction using the monopulse ratio of two SAR-imagery derived from the Σ and Δ-channels.
