Paper Abstract

A linear spectral estimator, referred to as the PDFT was previously used to reconstruct a target in a homogeneous background. More typically, a target will have other objects or noise around it. We address this problem for the general case of having several targets embedded in clutter and apply the PDFT to each target sequentially. We show that in such cases the regularization process and the choice of what prior knowledge is included in the reconstruction algorithm play key roles in obtaining a good image.
