Radar imaging of three-dimensional surfaces using limited data

Abstract

We consider the problem of radar imaging of 3-D targets, where conventional 2-D synthetic aperture radar (SAR) techniques are inadequate, because of range-Doppler ambiguities. This problem is cast into the form of a spectral estimation problem, which can be solved using a variety of methods. After giving an overview of two methods, ESPRIT and RELAX, we demonstrate this approach using simulated data.
