以提高定位精度为目的，同时从减少定位时延、消除定位模糊的角度出发，并且考虑到线阵定位角度范围的限制，提出了嵌套的均匀圆形麦克风阵列结构。由于在使用高分辨率的近场声源三维定位算法时会带来较高的计算复杂度，所以采用了宽带聚焦算法进行处理，使其时延得到较大幅度的降低。仿真结果表明，该方案取得了较好的定位效果。%In order to improve the localization accuracy,considering the linear array localization angle range limits at the same time,this paper proposed the nested uniform circular microphone array configuration to reduce the localization delay and elimi-nate the localization ambiguity.As the utilization of near-field acoustic source 3D localization algorithm with high resolution re-sulted in high computing complexity,it adopted wideband focusing algorithm to make the delay time being reduced greatly.Sim-ulation results show that this scheme has better localization effect.
