Superresolution ISAR imaging using 2-D autoregressive lattice filters

摘要

A new 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 two-dimensional (2-D) autoregressive modeling of 2-D Cartesian frequency backscattered data using 2-D orthogonal lattice filters. ISAR images obtained for an experimental target are included to validate this technique.
