　　　近20年来，阵列信号处理已成为信号处理的一个重要分支，本次实验就是通过MUSIC（Multiple Signal Classification）算法对混叠有高斯白噪声的双信源信号进行频谱分析。(Space there is more than one letter (No.) source, it is often necessary to separate these signals in order to track or detect the spatial signal we are interested in, inhibition of those who are considered interference signal. To this end, the need to use the antenna array to receive multiple spatial signal analysis and processing of the the spatial signal received by the antenna array known as array signal processing. The past 20 years, array signal processing has become an important branch of signal processing, this experiment is the MUSIC (Multiple Signal Classification) algorithm aliasing Gaussian white noise dual source signal spectrum analysis.)
