Signal Subspace Processing of Uncalibrated MTD-SARs

Abstract

This report provides a study on the merits of the algorithms that we have developed under this contract. For this purpose, we present moving target detection and imaging results for an X band spotlight SAR system that utilizes an along-track monopulse configuration for its data collection. The theoretical foundation of the processing that is used on these data is based on our work for this contract in which a two-dimensional signal subspace processing (adaptive filtering) method was developed to calibrate the monostatic and bistatic radars of the monopulse SAR system. The blind calibration of the two channels enables the user to null the stationary scene, and detect the moving targets. Next, a measure that we call SAR ambiguity function is used to estimate the relative speed of a detected moving target. The resultant estimate is then used to image the moving target.
