| Abstract | Near-field acoustical holography is a powerful tool for identify ing noise sources from partially known sound pressure field. Patch near-field acoustical holography (PNAH) is related to the partially measured pressure on the hologram surface in terms of sampling and bandlimiting matrices, which cost more in computation. PNAH procedure based on measuring of vector hydrophone array is described, including the mathematical formulation. The measurement array can been smaller than the source, thus the practicability and efficiency of this technology is greatly enhanced. Then an experiment has been carried out with vector hydrophone array. The experimental results have illustrated the high performance of PNAH and the advantages of a vector hydrophone array in an underwater near-field measurement. |
