| 摘 要： | 基于粒子群优化算法,以最大旁瓣级最小化为代价函数,在阿基米德螺旋线上搜索最优平面螺旋阵列。数值仿真计算利用粒子群优化算法搜索得到旁瓣级最低的最优阵列,与其他阵型比较,并在半消声室对各种声源进行声场测量和声源定位实验,验证了粒子群优化方法进行阵型优化的有效性。

| Abstract: | A novel method based on particle swarm optimization (PSO) is applied to search
for the optimal microphone arrangement on the Archimedes spiral line, which takes the side
lobe level as the fitness function. Numerical simulation with PSO indicates the optimal
arrangement of the array which shows its best performance compared with other configurations.
Experimental results of source localization and measurement in the semi-anechoic chamber
demonstrate the effectiveness of the proposed scheme |
