A State-Space Technique for Ultrawide-Bandwidth Coherent Processing.

Abstract

A scheme is presented for estimating the ultrawide-bandwidth position and typing of scattering centers on a target using sparse-band measurements. The algorithm determines a set of matrices that best describe the measured data, then the fitted data are used to interpolate between and extrapolate outside of the measurement bands. A modal decomposition approach is used to estimate the position and typing of the scatterers. Standard pulse-compression techniques are applied to obtain a highly defined range profile of the target; application of these techniques is followed by extended coherent processing to generate superresolved two-dimensional images. The effectiveness of the new algorithm is confirmed by computer simulations; it is tested further using static-range data on a canonical test object.
