Abstract :
Multi-dimensional high resolution is one of the most important factors in automatic target recognition (ATR) using the synthetic aperture radar (SAR) or inverse SAR (ISAR) images. In this work, we propose a resolution enhancement technique in three-dimensional (3-D) interferometric SAR/ISAR (IF SAR/ISAR) imaging using an iterative sidelobe apodization procedure.
