Abstract
DRDC Atlantic has developed a Clutter Model for range-dependent environments based on adiabatic normal modes. However, this approach is expected to fail for strongly range-dependent environments. Alternatively, parabolic equation (PE) models are robust in strongly range-dependent environments. In this study the DRDC PE model ‘PECan’ is used to determine the feasibility of computing reverberation and target echo fields in various ocean waveguides. Calculations are compared to problems from the US Reverberation Modeling Workshops. The PE Method reverberation estimates compare favourably to previously published results obtained by other authors and methods.
