主　　题：Microphone array 

摘      要：As the traditional time delay estimation algorithm can not accurately estimate the time delay between the microphone and vulnerable to environmental noise and other shortcomings, GCC algorithm was used and its improvement was used for time delay estimation. Ultimately a sound source localization system was implemented, combined with the microphone array designed by the author and the spatial orientation method was proposed. It can be calculated the distance and azimuth between the sound source and the target. After experimental verification, the sound source localization system can achieve high positioning accuracy, so it has some practical value.
