| 摘 要： | 研究了星形立体传声器阵列。利用粒子群优化算法对每条直线上的阵元进行优化排布,获得了具有较好指向性和较低旁瓣级的阵列阵型。基于优化得到的阵列阵型进行了星形立体传声器阵列的机械结构设计,设计的阵列主体能实现自如地折叠,便于包装和运输。研制了基于这种阵列阵型的声成像定位系统,通过数据仿真分析体现出优化设计阵型的优越性,同时通过实验验证了研制的声成像系统在声源定位中的有效性。

| Abstract: | A star-type 3D microphone array is developed. Particle swarm optimization algorithm is employed to obtain the optimal layout in each arm to form an ideal beam pattern characterized by the narrow mainlobe and low sidelobes. Based on the optimized array, the mechanical structure of the star-type 3D microphone array is designed. The main part of the array can be folded freely for easy packaging and transportation. Thereafter, an acoustic localization system is developed based on the optimally designed microphone array. The simulation and experiment are carried out to demonstrate the merits of the designed array configuration and to validate the localization capability of the developed acoustic system. |
