A Novel High Efficiency and High Accuracy 3D MIMO-SAR Imaging Algorithm

This paper presents a novel high efficiency and high accuracy three-dimensional (3-D) multiple-input-multiple-output synthetic aperture radar (MIMO-SAR) imaging algorithm. The result of an extended target with 8 sectors star are shown with the help of FEKO in this paper which is more sufficient and convincing compared with the usual point targets. Simulation results show that the algorithm can obtain the same high precision images as the back-projection (BP) algorithm with the same high efficiency as the range migration algorithm (RMA), while avoiding the tedious multi-dimensional interpolation.
