Abstract

Methods of solution were considered for solving the generalized coherence function when there is a general bottom impedance condition. In this case the equation contains a diffusion term. Three types of solution were considered: (1) a multi-scale solution, (2) a quasi-equilibrium solution and (3) a numerical marching procedure. Work on the numerical solution has begun using a simplified Gaussian form for the index-of- refraction fluctuation correlation function. In addition the bottom impedance condition has been compared with a formulation which includes a water-bottom interface and it is shown that the latter approach can be incorporated in the present formulation.
