Abstract:To effectively solve the underwater moving sound source of the noise source identification problem, the theory of Moving Sound Source Identification which is based on Mobile Framework Technology (MFAH)and the Helmholtz equation least squares (HELS) is investigated. Acoustic holography method based on MFAH and HELS is founded and experimental pond is verified. The experimental results show that the combination method can accurately identify underwater moving sound source .It can also obtain high source location accuracy and wide frequency range. When the complex sound field has Multiple coherent sound source, it only requires that the holographic array measurement of surface is 1.3 times more than the Surface reconstruction. Rapid identification about noise source localization movement which uses a small measuring surface is realized and it provides convenience for engineering applications
