A method and system for forming an image comprising at least one processor for performing the following: initializing an N by P image array Iby setting all values to a large number; inputting at least one image frame; randomly selecting and removing a subset of pixel locations from the total number of available pixel locations to form a preliminary image array I; for each pixel location comparing the complex magnitude of each pixel in the image array Iwith the magnitude of the corresponding pixel in image array I, and if the pixel value in the image array Iis smaller than the corresponding pixel in the image array Ior if the Ivalue equals 0, then the current pixel value in image array Iis replaced by the pixel value in the image array I; and repeating for a number of iterations to form an image.

Target detection utilizing image array comparison

Embodiments of the present invention generally relate to motion compensation, and in particular to an autofocus-based compensation (ABC) systems and methods for a ground moving target indication platform. According to one embodiment, a method for autofocus based compensation of range data acquired from an object in motion is provided. The method may include: receiving range data; steering at least one receive beam of the range data in a desired direction; transforming the range data into the range domain; determining the width of a main clutter lobe; excluding data that is not part of the main lobe clutter response; transforming the main-lobe clutter response into the range domain; calculating a phase correction term; and applying the phase correction to the original range data.
