A Three-Dimensional Location Algorithm of Near-Field Source Based on T-Type Sensor Array

基于传感器阵列来定位空间信源的技术在物联网、智能机器人、声学照相机、视频会议等领域中具有重要的应用价值和实用性,是阵列信号处理的热点研究内容。采用T型传感器阵列,基于阵列的对称性和经典的多重信号分类(MUSIC)算法,提出一种新的近场信源三维定位算法,相较于传统的多维MUSIC,只使用一维搜索,时间复杂度低并且定位精度也比较高。

The technology of locating spatial source based on sensor array has important application value and practicability in the fields of Internet of things,intelligent robot,acoustic camera,video conference and so on,which is the hot research content of array signal processing.In this paper,based on the symmetry of T-type sensor array and the classical multiple signals classification algorithm,a novel near-field three-di mensional source location algorithm is proposed.Compared with the traditional multi-dimensional MUSIC algorithm,this paper only uses one-dimensional search,with low time complexity and higher positioning accuracy.
