摘要：
In this paper, the research progress based on high-resolution spectral estimation in microphone array sound source localization is discussed. The application of Multiple Signal Classification (MUSIC) algorithm in sound source location is studied, and the effect of the algorithm in one and two dimensions is compared. Through the simulation experiments of one-dimension and two-dimensional MUSIC algorithm, the paper verifies the advantages of two-dimensional MUSIC algorithm in positioning accuracy compared with one-dimensional algorithm. In addition, the processing idea and flow of MUSIC algorithm are introduced in detail, including signal model, signal and noise subspace, sensor covariance matrix estimation, and spatial translation processing of related sources. The results show that MUSIC algorithm has high accuracy and reliability in sound source location, which provides an important reference for further application and research of sound source location technology.
