Superresolution ISAR imaging by 2-D complex asymmetric half-plane lattice predictors

Abstract

An efficient algorithm to obtain high resolution ISAR images in the case of limited frequency band and small angular section is presented. The method is based on the 2-D autoregressive asymmetric half-plane modeling of the backscattered data using a 2-D complex lattice predictor. The locations of the scattering centers are determined by the zeroes of the transfer function of the prediction error filter. A simulation example is included to show the performance of the algorithm.
