麦克风阵列技术是波达方向估计的代表性方法。通过使用这些技术，需要大量的系统硬件来获得尖锐的方向性特性。提出了基于参数估计方法的多声源定位的基本原理。讨论了波达方向估计的基本原理以及频率和相位估计技术。最后，实验结果证实了该方法的有效性。在嘈杂的环境中获得的实验结果也包括在内。
Microphone array technique are representative method for direction of arrival(DOA) estimation. By using these technique, a large hard ware amount of the system is required to obtain sharp directivity characteristics. The fundamental principle of multiple sound source based on the parameter estimation method is proposed. The fundamental principle of the DOA estimation and the frequency and phase estimation technique are discussed. Finally, the effectiveness of the proposed method is confirmed by the experimental results. Experimental results obtained in noisy environments are also included.
