The long-term goals of this effort are to Assess capability of directional arrays for inversion and reverberation studies Characterize acoustic clutter in a manner that will lead to its mitigation Improve geo-acoustic parameter extraction from reverberation data Construct suitable high fidelity reverberation and scattering models for modeldata comparison and inversion The objectives of this effort are to Continue validation and improvement efforts on a new reverberation model and investigate physics based clutter modeling. Use and continue to collect triplet array data from Five Octave Research Array FORA and the NURC arrays, conduct cross frequency correlation studies of scattering features to assess the utility of this technology for reverberation and clutter analysis both in the triplet frequency band above 600 Hz and at lower frequencies. Continue work on the automated geo-acoustic parameter extraction technique using reverberation data. Operate, maintain and improve FORA hardware and data acquisition systems. Help plan and participate in ocean experiments in support of sea floor scattering, sonar clutter studies and ocean reverberation experiments.
