摘要： 针对传统方法不能准确地测量远场多声源位置的问题,提出了在近场和远场都能用的多声源3D定位新方法.该方法采用两个L型麦克风阵列,在每个阵列通过多声源的频率及到达角的联合估计求得信号源的夹角,基于每个信号源的夹角对估计多声源的位置.通过仿真实验验证了该方法在近场、远场都能准确地测量多声源位置,通过调节两个L型麦克风阵列之间的距离能得到误差在5%以下的声源定位精度.

Abstract: In order to solve the problem that the traditional methods can not accurately measure the localization of multiple sound sources in far field, a new multiple sound sources localization method was presented that could be used in both the near field and the far field. This method adopted two L-shape microphone array, and in each array the signal's DOA was obtained by jointly estimating the DOA and frequencies of the signals. Finally, localization of multiple sound sources could be estimated based on the DOA's pair of two L-type microphone array. Simulation results indicated that the localization of multiple sound sources could be accurately measured in both the near field and the far field. By adjusting the distance between the two L-type microphone array, a standard deviation below 5% of the sound localization accuracy could be obtained based on the proposed method.
