dc.description.abstractIn general, the prediction of underwater radiated noise requires source level information. This study proposes a method for the source level estimation of propeller cavitation based on the beamforming method. The proposed method obtains the source level information by determining the source strength corresponding to the estimated cavitation position. As the solution of the minimization problem can be determined analytically rather than numerically, it has the advantage of fast computational time. The proposed method is verified through a model-scale test conducted in a large cavitation tunnel of Korea Research Institute of Ships and Ocean Engineering. The estimated source level of the propeller cavitation matches well with a transfer-function-based method in the frequency band that satisfies the far-field. In addition, another method for reducing the computational time is considered through determining the source level from the cavitation position and sound pressure level.-
