Abstract:

This is the Fiscal Year 2010 annual report by the PI to the US Office of Naval Research ONR for Grant N00014-06-1-0830 Measurements and analysis of reverberation, target echo, and clutter. The main accomplishments for the year were i completion of a report on monostatic reverberation calculations over a sloping bottom ii development of a bistatic range dependent clutter model that includes towed array beam patterns iii calculations of time spreading of scattering features and target echo and their effect on signal excess iv additional work on fathometer returns and reverberation at short times. The most significant accomplishment was the bistatic range-dependent clutter model based on adiabatic modes it is computationally efficient and is being implemented in the DRDC Sonar Test Bed for potential use by the Canadian Forces.
