Rapid Environment Assessment of Sea Bottom Parameters Using an Operational Active Low-Frequency Sonar
conference paper
The safety of the deployment of naval forces requires a correct estimation of sonar performances. The quality of these performances strongly depends on the knowledge of the environmental data, especially in shallow water environments where the acoustic field is particularly influenced by the interaction with the seabed sediment whose acoustic characteristics are rarely available.
Within this context, this paper describes a Rapid Environment Assessment method based on an inversion technique, and the results obtained during the European Defence Agency Project called “RUMBLE 2”. One of the objectives of this project funded from ministries of Defense of Norway, Sweden, Netherland and France and involving the previous four involved national teams was to assess that in shallow waters, performances of an operational Low Frequency Active Sonar (LFAS) can be improved by inverting in near real time the bottom parameters from the measured reverberation acoustic signal.
