一种新型半空域声源定位阵列

空域中声源定位主要利用传声器阵列TDOA技术实现,为了避免阵列自身精度对测量的影响和复杂的计算,提出一种结构简洁、计算便捷的平面十字形传声器阵列模型,并对声源定位的TDOA技术和这一模型在三维空间中的应用进行了分析,给出了定位算法和误差公式,通过实验论证了该阵列模型在构造、计算等方面的优势.所构造的系统虽然在精度等方面有待进一步提高,但其对无源定位的研究方法和所构造阵列较强的实用价值在各类传声器阵列技术领域中有着广泛的应用前景.

New Kind of Planar Microphone Array in Half-Aerial Acoustic Source Location

The acoustic source location is mainly implemented by the TDOA technique with microphone array,and its accuracy related with the array's structural parameters.To avoid the influence in the accuracy from array of itself and the complicated calculation,crossed microphone array model have been put forward with simple and direct structure.Location arithmetic,error formulation and data of measured value have been given in the study of this array by TDOA.Although this system needs to be improved in many direction...
