Résumé

The standard method of determining the directional properties of underwater acoustic fields is to coherently combine the weighted pressure field measurements made by spatially distributed sensors. An alternative approach is to make measurements of other properties of the acoustic field, in addition to pressure, at single points in space. For example, measurements of acoustic particle velocity can be combined multiplicatively with those of pressure to determine the vector acoustic intensity. The purpose of this presentation is to discuss the relationship between the information obtained on the directionality of the sound field by the standard beamforming techniques and vector acoustic intensity
