Image Quality SAR Refocus of Moving Targets undergoing Complicated Rolling Maneuvers

Moving targets typically appear smeared in synthetic aperture radar (SAR) imagery, often making the task of target recognition more difficult. Recently, research has yielded an ability to perform Arbitrary Rigid Object Motion Autofocus (AROMA) to generate automatically focused target images for cases of arbitrary target rotation and translation during the coherent processing interval of SAR collections. The current research analyzes the efficacy of AROMA processing for targets undergoing complicated rolling maneuvers against a background of measured Ku-band image clutter. The results of this analysis reveal that AROMA can yield focused target imagery that correlates well with the true structure of the target.
