High-frequency source localization in the Strait of Sicily

摘要: One of the keys for a successful inversion acoustic data using matched-field processing (MFP) technique is amount environmental and geometric information available. When this missing or erroneous then one in presence model mismatch. To work at higher frequencies provides better discrimination range depth but also increases dependency algorithm on mismatch which, practice, leads to tradeoff between The ADVENT'99 sea trial took place area Adventure Bank Strait Sicily during May 1999, with objective testing MFP techniques. A 62-m aperture vertical line array was deployed 2, 5 10 km from an source. source emitting series multi-tone signals band 800-1600 Hz. This paper tests two step frequency 2 tracks: first pre-focused genetic search where parameters are estimated second exhaustive performed depth.
