提出了一种基于时域等效源方法的时域反演技术，用于旋转声源的定位和量化。在该技术中，实际旋转声源由分布在源表面上的一系列旋转等效源建模。这些等效源的强度是根据接收器时间测量的压力与源时间所需的等效源强度之间的精确传递关系来求解的。与已知的仅具有声源定位功能的时域旋转波束形成相比，所提出的逆技术不仅可以精确定位旋转声源，而且可以定量预测声场。此外，由于使用延迟时间方法，所提出的反演技术避免了时域旋转波束形成中所需的测量压力的插值，从而提供了实时计算源强度的能力。数值模拟和实验验证了该技术的有效性，并通过与时域旋转波束形成进行比较，证明了其更准确地定位声源并能够定量预测声场的优势。
A time-domain inverse technique based on the time-domain equivalent source method is proposed for the localization and quantification of rotating sound sources. In this technique, the actual rotating sound sources are modeled by a series of rotating equivalent sources distributed on the source surface. The strengths of these equivalent sources are solved based on the exact transfer relationship between the measured pressure at the receiver time and the desired equivalent source strengths at the source time. Compared to the known time-domain rotating beamforming that just owns the function of source localization, the proposed inverse technique not only can locate rotating sources accurately but also can predict sound fields quantitatively. Moreover, due to the use of retarded time approach, the proposed inverse technique avoids the interpolation of measured pressure that is needed in the time-domain rotating beamforming, thus providing the ability of real-time calculation of source strengths. Numerical simulations and experiments examine the validity of the proposed technique and demonstrate its advantages of locating sources more accurately and enabling to predict sound fields quantitatively by comparing with the time-domain rotating beamforming.
