We present a synthetic aperture sonar beamforming engine called ASASIN. ASASIN is a graphics processing unit based time-domain backprojection beamformer for Windows and Linux utilizing the NVIDIA architecture. It supports arbitrary array geometries and has a modular data input system. ASASIN uses one or more graphics processing units to beamform synthetic aperture sonar data faster than real-time. Its interface is suitable for operators and research scientists. In this talk we discuss ASASINs algorithms and computational performance along with the choices confronted (both algorithmic and computational) in its design. Finally, we discuss its computational performance across a variety of NVIDIA graphics processing units including their embedded models.
