FPGA-Based Sonar Processing
Abstract
This paper presents the application of time-delay sonar beamforming and discusses a multi-board FPGA system for performing several variations of this beamforming method in real-time for realistic sonar arrays. Additionally, we show that our proposed FPGA system has a six to twelve times performance advantage over an equivalent system created using currently available, high-performance DSPs designed for multiprocessing systems. This performance advantage is due to the simplicity of the core calculation, the limitations of the the DSP s address calculation hardware, and the ability to customize the I/O of the FPGA to the application.
