MIMO Radar Hardware Acceleration with Enhanced Resolution

This paper proposes a method for accelerating an enhanced resolution 3D (range, velocity, and azimuth) Multiple Input Output (MIMO) radar on Graphics Processing Unit (GPU). Implementation of MIMO radars the investigation their performance are interest to research community. However, mode operation increases computational requirements system seldom permits real-time without compromises. Current methods achieving reasonable frame rates include reducing scope (i.e., limiting number dimensions, field view, or ranges interest), choosing efficient but coarse algorithms FFT range, bearing estimation), offloading computation task specific hardware, DSP, FPGA. The proposed framework enables by performing signal processing GPU compromising coverage, while replacing widely used with alternative. is tested Frequency Modulated Continuous Wave (FMCW) using 8 transmitters, receivers, having Coherent Interval (CPI) 256 chirps. parallel implementation yields acceleration 453.6x when compared sequential execution CPU.
