Abstract： Broadband acoustic holography based on intensity measurement (BAHIM) is a new technique which developed for the reconstruction of sources using near-field acoustic holography (NAH). With the sound intensity distribution on a measurement cylinder, it can obtain the complex sound pressure phase on the measurement cylinder and predict the complex sound pressure. Appling this method to identify the noise source in underwater cylindrical interior, the principle of the cylindrical BAHIM is presented. The numerical simulations have been conducted. At last, the validity and correctness of vector hydrophone array is assessed by underwater near-field acoustic holography experiments. The results of experiment using vector hydrophone array show the merits of the underwater cylindrical interior BAHIM in the reconstruction of sound field, identification and localization of the noise sources.
