| Abstract: | In order to study the method of calibrating the very low frequency(VLF) vector hydrophone in water tank,regularity for change of the near-source field is studied through numerical modeling for the sound field in water tank,considering the influence of source position,water tank size and so on.The study indicates that the near field excited by a continuous signal is characterized as a quasi-spherical wave,and can be used to calibrate VLF vector hydrophone.Besides,the study presents the calibration method in ... |
