In this paper, moving sound source and/or receiver with arbitrary trajectory is implemented in the two-dimensional finite difference-time domain (FDTD) method. Two methods are proposed to implement a moving point source and/or receiver in the FDTD method in which physically valid analysis is possible including Doppler effect. One is the direct method and the other is the convolution method. The formulations and numerical experiments are made for the two-dimensional sound field, and the accuracy of two proposed methods are compared. It is confirmed that both methods can be applied to moving sound source and/or receiver including Doppler effect, and that two method have the almost same accuracy. It is found that the convolution method has advantages that the source waveform and moving speed can be freely changed at the time of convolution when either the source or receiver is stationary. |
