摘　　要：同时具备上下半球声源无模糊定位能力和获得较高的定位精度,是麦克风阵列技术的重要研究问题之一.提出了一种锥形六元麦克风阵列,分析了其定位性能,并把它们与传统的平面四元阵的有关指标进行了对比.结果表明,锥形六元阵不仅具备全视角声源定位能力,定位精度较平面四元阵有普遍提高,并且消除了有效声速和阵形参数对角坐标估计精度的影响.It is remarkable to locate an aerial sound source with a microphone array as accurately as possible clearly. A six - microphoned cone-shaped array and its performance are presented. Analysis shows that the novel array not only be capable of locating a sound omnidirectionaly with much more accuracy compared with a traditional tow dimensional four -microphoned array, but also gets rid of the locating accuracy limit from the virtue sonic velocity and the array structural parameters.
