摘要
利用无人机挂载测量设备结合定位系统,采取飞行测量的方法对扬声器阵列的远场声学参数进行了测量分析。利用计算机程序筛选和处理测量数据,得到了扬声器阵列的远场声辐射特性。通过分析飞行测量系统的构成和测量原理以及对比理论仿真结果与实测结果的一致性,验证了飞行测量方法的可靠性。
Far-field acoustic parameters of the loudspeaker array are measured and analyzed by using UAV carrying measurement equipment and positioning system.Far-field acoustic radiation characteristics of the loudspeaker array are obtained by selecting and processing measured data with computer.The reliability of the UAV flying measurement method is verified by analyzing the composition and measurement principle of the system and comparing the theoretical simulation results with the measured results of it.
