Studies on Sonar Clutter and Reverberation

Abstract

The objectives of this effort are to: (1) 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 approx. 600 Hz) and at lower frequencies; (2) Continue validation and improvement efforts on a new reverberation model and investigate physics based clutter modeling; (3) Continue work on the automated geo-acoustic parameter extraction technique using reverberation data; and (4) 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.
