  • 由于运动声源测量信号中多普勒效应的存在,一般声全息方法无法直接使用,而阵列信号波束成形处理方法无法进行定量分析.本方法建立了基于测量面、辐射面和全息面的运动学几何关系,提出了声源与测量信号之间的非线性时间映射方法,基于运动声源的声源特征函数,构造了消除多普勒效应的全息面时域声压分布.全息重建得到运动声源表面有效声压分布,实现了对主要声源处声压幅值的定量估计.实际运动声源的测量实验结果证明了该方法的有效性.
    The conventional acoustic holography method is not suitable for the measurement of the moving sound source, because the Doppler effect exists in the sound signal, and the beam-forming approach is unable to make quantitative analysis. The approach proposed in this paper establishes the time-space relation between the measurement field, the radiating field and the acoustic holography field, and puts forward a method of nonlinear time-mapping between the sound source and the measured signal. Based on the acoustic source eigen-function, the acoustic pressure distribution of the acoustic holography field in the time domain is obtained, in which the Doppler effect is eliminated. The sound field of the surface of the moving sound source is reconstructed by acoustic holography method, and the quantitative analysis of the major sound source is realized. This method has been used in the experiment of measuring the moving sound sources, and satisfactory results proved the effectiveness of the method.
