系统地研究了基于麦克风阵列的声源定位方法，提出了一种基于空域互相关矩阵的延时估计方法。通过仿真实验证明该方法简单、直接，并且能够在增加麦克风数量的情况下很好地抑制噪声和混响所带来的影响。

This paper systematically studied the method of sound source localization based on microphone array .A spatial cross correlation matrix based TDE algorithm is proposed in this dissertation .This approach can take advantage of the re-dundancy when more than two microphones are available and to help the estimator running better with noise and reverbera-tion .Some simulations verify the performance of proposed algorithms .
