Abstract

In this work, the problem of scatterer separation in SAR imaging is considered. We discuss a solution based on the annihilating filter method (AFM), which allows joint estimation of range and complex reflectivity of targets within a resolution cell. We show that with Cadzow denoising procedure, the algorithm produces good frequency and amplitude estimation results. The performance of the algorithm compares favorably with the performance of DFT and MUSIC.
