MFP-REA Follow-Up 2002-2005

Abstract

Acoustic propagation in shallow water depends among others on the composition of the sea bottom. It is very desirable for the navy to use passive acoustic methods instead of active, to acquire knowledge about this composition. The intention of the Matched Field Inversion - Rapid Environmental Assessment project is to use ambient noise received on a vertical array for this bottom classification. To exploit the limited information content of ambient noise, a well chosen geoacoustic model is required, together with an efficient optimisation algorithm and an educated interpretation of the inversion results. This combination of knowledge has resulted in several articles, which are summarised in this report.
