Abstract
The analytical algorithm developed in this work is intended for modeling wave fields at extremely long distances; it has no limitations on accuracy, media models, and observation databases and makes it possible to calculate the dynamics of individual waves (primary waves, ghost waves, etc). Comparison with experimental marine data is performed with a program developed for the calculation of wave fields. The modeling performed shows that the incorporation of absorption in the Earth ensures a good agreement between the model and the observed wave fields. The formula for the ratio between waves of different multiplicities corroborated by experimental and mathematical modeling data is obtained to a first approximation for large source-receiver separation. An analytical modeling of full wave fields has been performed, some types of waves are analyzed, and the physics of multiple waves in a layer of water is studied numerically
