Recent work with the spectrum-parted linked image test (SPLIT) uses polarization with Fourier-based peak detection to qualify pixels for attributed scattering center (ASC) extraction from synthetic aperture radar (SAR) phase history data. SPLIT is a two-stage, non-linear technique to extract ASCs. The first stage qualifies pixels for ASC attribution, but suffers from imaging sidelobe energy. Error in pixel qualification propagates to stage two: pixel attribution. In this work, a new ASC extraction method is proposed. It is based on 2-D Prony method and motivated by SPLIT. Position estimation performance of SPLITs local peak detection is compared to the 2-D Prony method. 2D-Prony achieves up to 70 percent accuracy at 20dB signal-to-noise while local peak detection achieves up to 20 percent correct pixel qualification. In addition, correct pixel attribution for primitive shapes is shown to achieve 80 percent using 2-D Prony method and up to 98 percent using local peak detection. Although seemingly contradictory results, physical reasoning may explain the lower correct qualification rate with a higher attribution rate. Lastly, we present measurement methodology for complimenting the modeling and simulation methods.
