Abstract

In order to locate the underwater sound in the complex acoustic environment, a localization algorithm based on the modal amplitude correlation is improved. The received acoustic field data was converted from hydrophone domain into modal domain. The modal amplitudes affected slightly by environmental mismatch were selected, and the corresponding modal amplitudes of the copy were extracted from copy of the acoustic field which was calculated by simulation model. The MVDR processor was used to match the two to realize the underwater sound source location, and the location effect was compared with the Bartlett processor. Finally, the accuracy of the MVDR method of underwater sound source location based on modal amplitude correlation was verified by the experiment at sea.
