Abstract
The paper presents a new inverse synthetic aperture radar (ISAR) algor ithm intended for radar cross-section (RCS) imaging and measurement fr om scattered fields. The method, based on a spherical-wave near-field illumination of the target, overcomes the requirement for an expensive compact range facility to produce a plane wave illumination. The form ulation and the implementation of the algorithm are described. Some ex perimental results obtained in an anechoic chamber are presented to sh ow RCS results similar to the conventional plane wave methods.
