ABSTRACT:
This autofocus is a system for improving the image quality of an airborne Synthetic Aperture Radar (SAR), that is mechanized in the high-speed digital signal processors with some control capability from the operating console to perform on-line focusing, to provide a unique and superior focusing technique. It includes (a) selecting the range bins which contain the strongest signals; (b) forming the subapertures from the end pulses in the selected range bins and performing map correlations; (c) judging the quality of each map correlation by its associated discriminate and determining the best one; and (d) generating the correcting phasors based on the best correlation and correcting the radar data accordingly.
