Abstract
Embodiments of methods, apparatuses, and articles for receiving phase history data collected from synthetic aperture radar imaging of a terrain, dividing the received phase history data into a plurality of subsets corresponding to a plurality of subaperture intervals, computing for each of a plurality of points of the terrain, a contribution of each of the plurality of subaperture intervals, each contribution including a magnitude and a phase calculated by interpolating the subaperture interval, using the corresponding subset of phase history interval data, and based at least in part on an arbitrary reference surface's elevation at the point, summing for each of the plurality of points of the terrain, the contributions of the plurality of subaperture intervals, and forming an image of the terrain based at least in part on the summed contributions of the plurality of subaperture intervals to the plurality of points of the terrain, are described herein.
