Graphics Processing Unit's (GPU's) powerful compute engine is leveraged to enhance the stand-alone capability of a central processing unit (CPU). Synthetic Aperture Radar (SAR) algorithm is analyzed and implemented to execute on a system equipped with a graphics card. Being a combined CPU/GPU solution, optimizations were applied to both architectures for optimal hardware utilization.
