Abstract 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. © 2002 John Wiley & Sons, Inc. Microwave Opt Technol Lett 32: 81–85, 2002.
