介绍了利用声矢量传感器在自由场中对多声源进行定位的方法和初步结果。基于傅立叶分析支持的声强法，确定了所考虑声源的波达方向。所获得的所考虑信号的频谱分量允许独立地确定特定频率的DOA值。在实验室测试的基础上，对所开发和实际实现的算法的准确性进行了评估。在测量过程中使用了合成声学信号(纯音和噪声)和真实声音。真实信号在时间域和频域具有相同或不同的能量分布。文中详细介绍了实验装置的设置和所获得的结果。考虑到所获得的结果，重要的是强调使用单个声矢量传感器来定位多个声源是可能的。对于光谱能量分布不同的信号，定位精度最好。
Method and preliminary results of multiple sound sources localization in free field using the acoustic vector sensor were presented in this study. Direction of arrival (DOA) for considered source was determined based on sound intensity method supported by Fourier analysis. Obtained spectrum components for considered signal allowed to determine the DOA value for the particular frequency independently. The accuracy of the developed and practically implemented algorithm was evaluated on the basis of laboratory tests. Both synthetic acoustic signals (pure tones and noises) and real sounds were used during the measurements. Real signals had the same or different energy distribution both on time and frequency domain. The setup of the experiment and obtained results were described in details in the text. Taking the obtained results into consideration is important to emphasize that the localization of the multiple sound sources using single acoustic vector sensor is possible. The localization accuracy was the best for signals which spectral energy distribution was different.
