Abstract :
The paper describes a new method for acoustic ray tracing. The method is based on the concept of a travelling wavefront, which leads to a new formulation and a simple algorithm for ray tracing. The approach is suitable for arbitrary sound speed profiles which can be approximated by differentiable functions. It does not require linearisation and is particularly convenient for computer simulations. It can be easily generalized to include range-dependent cases in which the sound speed profiles change with the horizontal distance. Several examples are presented to illustrate the usefulness or the method and to assess its accuracy
