In order to improve the identification of moving sound sources and solve the ghost source problem, the short-time wave superposition relation for moving sound source is established according to the Doppler frequency shift in short time, the equivalent sound source is pre-estimated by beam-forming, based on the pre-estimation result, the wave superposition equation is developed and the sound source is calculated by solving the equation. Then the dynamic wave superposition method for moving sound source is obtained. This method extends the wave superposition method to the case of the moving sound sources and solves the ghost source problem in moving sound source identification without adding extra microphones or changing the layout of microphone array. This method is used in the experiment to measure the moving sound sources, and satisfactory results prove the effectiveness of the method.
