Abstract:

The vertical directionality of ocean ambient noise as a function of frequency, depth, geographical position, and season is desired to properly model candidate array systems performance. To allow such measurements independent of array suspension noises, the use of SONODIVER is planned. This note documents the potential capability of three array lengths to cover the frequency band 5 Hz to 2000 Hz. Each array has five hydrophone sensors which will be instrumented and vertically suspended from the SONODIVER II vehicle, and recorded on analog magnetic tape. The data will be analyzed by sophisticated beamforming computer methods. The results show that this can be accomplished by randomizing the sensor placement along the vertical line and having array lengths of 300 ft, 60 ft and 12 ft.
