Advanced multiple input multiple output (MIMO) SAR algorithm for high-resolution 3D reconstruction imaging

In this paper, an advanced multiple input multiple output (MIMO) SAR algorithm for high-resolution three-dimensional reconstruction imaging was proposed. Firstly, we give a short overview of the principle of scattering mechanism and the formulations of optimized physical optics (PO). Additionally, a three-dimensional(3D) MIMO SAR array is illustrated. Finally, NVIDIA's Compute Unified Device Architecture (CUDA) is used to parallelize and accelerate the Electromagnetics (EM) simulation and imaging process in a Graphics Processing Unit (GPU). An electrically-large target, Airbus A380, was computed and the 3D reconstruction image was presented.
