In order to enhance the searching performance of robot hearing system in three-dimensional space and increase the adaptability in actual noisy environment, a multi-source target positioning system based on time delay of arrival (TDOA) was presented. The localization of target was carried out through the regular tetrahedron microphone array architecture on multi-source. The whole system was divided into four parts including the signal acquisition and preprocessing, blind source separation, multi-source positioning and robot control. Experiments results show that the design can make the robot find the position of many sources and reach the target rapidly and accurately. Source
