Abstract:

For the error problem of space spectrum estimation algorithm in the practical application,the background of the amplitude and phase error exists in the array is discuased,a method of MUSIC(Multiple Signal Classification) algorithm is realized in DSP(Digital Signal Processor).Through the setting position accurate auxiliary source of amplitude and phase error correction,the orientation of the auxiliary array information for error parameters provided the necessary information,and then the MUSIC algorithm of wave direction estimation,at the same time use high-speed DSP chip(TMS320C6713) of TI company to implement MUSIC algorithm under the background of the amplitude and phase error in the array.The simulation results prove the effectiveness of this method.

Key words: amplitude and phase error, multiple signal classification(MUSIC), digital signal processor（DSP）, direction of arrial (DOA)
