Abstract :
We develop time reversal spotlight synthetic aperture radar (TR-SAR) for target focusing and ghost images removal in SAR. Conventional SAR is not designed for imaging targets in a rich scattering environment. In this case, ghost images due to secondary reflections appear in the SAR images. We show in this paper, how, from a rough estimate of the target location obtained from a conventional SAR image and using time reversal, TR-SAR focuses on the target with improved resolution, and reduces or removes ghost images. Verification with experimentally measured electromagnetic data demonstrates the success of TR-SAR.
