Paper Abstract

The purpose of this paper is to address the use of an autoregressive method to discern scattering center distribution. This information serves the purpose of a filter that is utilized to determine the minimum-weighted-norm least-squares solution of the autoregressive parameters. The parameters are employed to extrapolate a set of wideband target signatures collected in the spatial-frequency domain. The periodogram of these signatures yields a profile history or an image with high resolution and accurate reflectivity measurements. The iterative autoregressive method is compared to the principal component modified covariance to illustrate performance improvement.
