Abstract

The implementation of frequency and angle measurements of L-Array based on designed FPGA+DS P system is studied in this paper. The proposed processing methods is discussed with real data, the peak searching MUSIC algorithm and the unitary transformation root MUSIC algorithm are both implemented in DSP, and the processing results show that the time of unitary transformation root MUSIC algorithm is faster than that of peak searching MUSIC algorithm by 62.6% at the same precision level. The unitary transformation root MUSIC algorithm can also find the wideband signal in the experimentation.
