摘　　要：针对传统的时延估计算法不能精确地估计出麦克风之间的时延和易受环境与噪声影响等缺点,利用广义互相关(GCC)算法进行时延估计并对其进行改进,结合自行设计的小型麦克风阵列和提出的空间定位方法,最终实现了声源定位系统,可以计算出声源与目标之间的距离和方位角.实验表明:本声源定位系统能达到比较高的定位精度,具有一定的实用价值.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.
