| 中文摘要: |
| 对阵列的特性进行了研究,并提出了一种优化的64阵元平面螺旋阵列。这种64阵元平面螺旋阵列的阵元分布在以阵列中心为轴心的8条螺旋上,并且具有较窄的主瓣宽度和较低的旁瓣级。基于这种优化的阵型,研制了一种声源定位系统。研究分析了该阵列的探测性能,并通过实验数据对该声源定位系统的性能指标作了验证和评估。利用波束形成算法进行声源定位,通过仿真和实验分析,证明了这种阵型优化的阵列在声源定位应用中的有效性。 |

| Array features are investigated and a geometric optimized planar array of 64 microphone elements is proposed.The microphone elements are distributed along 8 helixes,and the proposed planar array possesses narrower main-lobe and lower side-lobes.Based on this optimized planar array,a source localization system is developed.The feature and performance of the proposed source localization system are evaluated and analyzed based on the data recorded in a semi-anechoic chamber.Beam-forming algorithm is used in the source localization system.Simulations and experiments are carried out to validate the effectiveness of this microphone array in source localization. |
