Measurements and Analysis of Reverberation, Target Echo, and Clutter

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.
