摘要：

The paper presents a method for calculating frequency-dependent rays, which allows effective approximation of a broadband signal propagation. We provide comparative analysis of this method with the standard ray method and the finite-difference method. The developed algorithm is promising for modelling and inverse problems. We performed the numerical examples for the realistic Sigsbee model.
