Paper Abstract

A new formulation of the problem of high-resolution radar-imaging is given. We consider a diffuse radar-target for which the reflectivity is modeled as a complex-valued Gaussian ran-dom-process with a mean of zero and an unknown covariance function. Delay-doppler measurements containing additive noise are made by illuminating the target with a sequence of pulses of arbitrary shape. An algorithm for estimating the target's scattering function from these measurements is derived using the method of maximum-likelihood estimation and the concept of an incomplete/complete data-model. The reflectivity process is also estimated.
