| 摘 要： | 对行驶车辆辐射声场的阵列信号处理理论进行了应用性研究。参照空间域信号相关函数理论,提出基于相关函数的波束形成方法。通过系统仿真验证,利用该理论进行的空间信号扩展可以使信号接收阵列所需的传声器数目大幅降低,同时对声源定位结果精度影响不大。

| Abstract: | The array signal processing method,which is used to orientate the sound source of the moving vehicle,was studied in this thesis.And a beamforming method based on spatial correlation function was advanced.The theory was researched in the simulation,and the results proved that the infection in precise of the rebuild result would be little,meanwhile,the needed microphones in the array would be much less. |
