阵列幅相误差背景下MUSIC算法的DSP实现

针对空间谱估计算法在实际应用中的误差问题，讨论了在存在阵列幅相误差背景下，多重信号分类法(MUSIC：MUltiple SIgnal Classification)测向算法在DSP(Digital Signal Processor)上实现的一种方法。通过设置方位精确的辅助阵元对幅相误差进行校正，辅助阵元的方位信息为误差参数的计算提供了必要的信息量，然后利用MUSIC算法进行波达方向估计，同时利用TI公司高速DSP芯片(TMS320C6713)实现了在阵列幅相误差背景下的MUSIC测向方法。仿真结果证明了该方法的有效性。

DSP Realization of MUSIC Algorithm under Background of Array Error of Amplitude and Phase

For the error problem of space spectrum estimation algorithm in the pr actical application,the background of the amplitude and phase error ex ists in the array is discuased,a method of MUSIC(Multiple Signal Classification) algorithm is realized in DSP(Digita l Signal Processor).Through the setting position accurate auxiliary source of amplitu de and phase error correction,the orientation of the auxiliary array informatio n for error parameters provided the necessary information,and then the MUSIC al gorithm 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 simulati on results prove the effectiveness of this method.
