Abstract :
We present an estimation-theoretic approach for reducing motion effects in SAR imaging. Our approach may be viewed as a multi-dimensional matched-filter, whose parameters are determined by the relative motion between the SAR antenna and the target. In contrast to similar multi-dimensional matched filter methods, we propose a fast and easily implementable solution
