Paper Abstract

Interferometric moving target focusing (IMTF) is an interferometric SAR technique which enables high resolution detection, tracking, and imaging of moving ground targets. While IMTF is able to reliably extract clutter canceled moving ground target signatures from three channel interferometric data, traditional SAR autofocusing techniques are unable to reliably focus moving ground target imagery. Because moving ground target motion includes undesired target roll, pitch, and yaw, and for some vehicles, nonrigid body characteristics, more sophisticated autofocusing techniques are needed. This paper briefly presents IMTF and high resolution IMTF imagery. The paper describes promising techniques for the improved focusing of moving ground target imagery. Image improvement is demonstrated by comparing a modified phase gradient autofocusing technique with the unmodified version.
