Real-time Implementation of Multiple Sub-array Beam-space MUSIC Based on FPGA and DSP Array

摘要：

Multiple sub-array beam-space MUSIC (MSBMUSIC) 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 based on CORDIC and the eigenvalue decomposition using the two-side CORDIC based parallel Jacobi algorithm are implemented on the FPGA. The calculation of the covariance matrix and MUSIC angular spectra are implemented on DSP array,respectively. The parallel processing platform has been applied to the shallow water high resolution multi-beam echo sounder,and the lake test proves that the system can achieve the high performance.
