Abstract

Moving targets are often smeared in synthetic aperture radar (SAR) imagery beyond recognition. Recent analysis has yielded an ability to perform Arbitrary Rigid Object Motion Autofocus (AROMA) in order to perform automatic refocus of targets which exhibit arbitrary temporal profiles of target translation and rotation during the SAR collection interval. This investigation examines the efficacy of AROMA for targets with complex heading profiles amidst a background of measured Ku-band SAR imagery. It is found that AROMA is able to generate well focused imagery which corresponds with the underlying true structure of the target scattering shapes.
