Ocean-acoustic Raytracing Propagation Models Based On Fermat's Least Time Principle
Considering Fermat's least time principle we developed 2D and 3D ocean-acoustic raytracing propagation models. Each one consists of an algebraic differential system of equations. So, considering Fermat's least time principle we developed 2D and 3D ocean-acoustic parametric raytracing
propagation models based on the Euler-Lagrange equations. Each one consists of an algebraic differential system of equations. Numerical simulations were presented, discussed and compared with propagation predictions obtained with a consolidated tool developed and utilized by the scientific
community.
