Abstract

This paper presents a method of forming synthetic aperture radar, SAR, images of moving targets without using any specific knowledge of the target motion. The new method uses a unique processing kernel that involves a 1D interpolation of the deramped phase history which we call Keystone formatting. This preprocessing simultaneously eliminates the effects of linear range migration for all moving targets regardless of their unknown velocity. Step two of the moving target imaging technique involves a 2D focusing of the movers to remove residual quadratic phase errors. The third and last step removes cubic and higher order defocusing terms. This imaging technique is demonstrated using SAR data collected as part of DARPA's Moving Target Exploitation program.
