In this paper, the focused image formation problem of inverse synthetic aperture radar (ISAR) data collections that use wide angular apertures are considered. A two-dimensional near-field back-projection algorithm is presented which compensates the range migration effects resulted from wide-angle data collection set-up. The algorithm is applied to a hypothetical target model and validated through the produced wide-angle near-field ISAR image. Resolution measures for wide-angle data collection scheme and imaging are also evaluated by comparing the impulse response functions.
