Improving spatial domain based image formation through compressed sensing

Author: Stoltz, George G ; Nel, AL Date: Oct 2020 In this paper, we improve image reconstruction in a single-pixel scanning system by selecting an detector optimal field of view. Image reconstruction is based on compressed sensing and image quality is compared to interpolated staring arrays. ... Read more
Investigation of 3-D RCS Image formation of ships using ISAR

Author: Lord, RT ; Nel, Willem AJ ; Abdul Gaffar, MY Date: May 2006 Conventional Inverse Synthetic Aperture Radar (ISAR) utilises the rotational motion of a target such as a ship or an aircraft to obtain a 2-D image of the target’s radar cross section (RCS) profile from a coherent radar system. This concept ... Read more
Performance estimation of a real-time Rosette imager

Author: Stoltz, George G ; Stoltz, M Date: Sep 2020 In this paper, we model a real-time feasible rosette imager, consisting of a rosette scanner, an optical sensor and a deterministic image reconstruction algorithm. We fine-tune the rosette imager through selecting the appropriate sensor field ... Read more
