This paper introduces an underwater acoustic / optical integrated imaging system, which individual uses the DSP core and ARM core of the OMAP3530 processor to realize the multi-subarray amplitude-phase united detection algorithm and optical camera image collection for getting the estimating the depth of the sea and the optical information of the focus area uses the ARM core to receive the GPS and...
Multiple sub-array beam-space MUSIC (MSB-MUSIC) is a new beam-space high resolution DOA estimation algorithm. In order to solve the problem of huge computation load of the algorithm, a real-time processing scheme based on FPGA and DSP array is proposed and implemented on the hardware. In the hardware platform MSB-MUSIC with 80 channels data is real-time implemented, where both the digital down conversion...
This paper presents a Shallow water High Resolution Multi-Beam Echo Sounder (SHMBES), which will be used widely in modern ocean exploration and underwater engineering. It is highly synthesized and developed on the basis of many new techniques such as theories of underwater acoustic and modern signal processing, Very Large Scale Integration (VLSI), DSP array processing, etc. It is mainly composed of...
