ABSTRACT:--   This paper presents a phase-preserving algorithm for processing ScanSAR data, based on modifications to the well-known RD algorithm.    The azimuth compression stage is modified to isolate each target's energy within the burst regimes. Analysis and simulations verify the phase accuracy of the modified algorithm.

This paper was presented at IGARSS'97, Singapore, August 3-8, 1997, and is published on pages 725-727 of the proceedings.    The UBC work was supported by the NSERC/MDA Industrial research Chair in Radar Remote Sensing.
