High resolution through-the-wall radar imaging using extended target model.

Through-the-wall radar imaging attempts to image complex scenes within enclosed structures. While most of the high-resolution imaging techniques assume point targets, indoor imaging requires dealing with single or multiple walls which are extended targets in nature and violate the point-target assumption. In order to provide high quality imaging, we need to consider point targets and extended targets separately. In this paper, we model extended targets and apply signal subspace methods for target localization. By combining two separate images, one with point target model and the other with extended target model, both types of targets can be identifiable. Imaging results are shown with both synthesized and experimental data.
