中文摘要：

基于声达时间差（TDOA）和正四面体麦克风阵列的声源定位模型中,影响定位的精度的因素除了阵元安装的位置误差、时间延迟和环境噪声之外,还受到阵列自身位姿的影响,麦克风阵列位姿的不确定,其直接导致声达时间差的不确定,进而影响定位结果,以全范围内声源目标定位为应用背景,利用基于RBF神经网络声源定位模型研究麦克风阵列位姿的不确定对声源定位误差产生的影响.

英文摘要：

The precision of sound source localization model based on the time difference of arrival （TDOA） and tetrahedral microphone array is affected not only by the installation location of the array element error, time delay and ambient noise, but also by the microphone array pose. The unpredictability of array pose causes directly the uncertainty of time difference of arrival, and it influences further the results of localization. Taking the full range of the target sound source localization application as the background, the RBF neural network model of the sound source localization were used to research the microphone array pose uncertainty on the impact of sound source localization error.
