Influence of Range-Dependent Sound Speed Profile on Position of Convergence Zones

Based on the Wentze–Kramers–Brillouin approximation, we derive formulae to calculate position of convergence zones in a range-dependent environment with sound speed profiles varying linear and ellipsoidal Gaussian eddy cases. Simulation results are provided for Experiment data used calculations considering linearly speed, findings suitably agree simulation results. According evaluated environment, influence profile upper lower different source depths is analyzed through simulations. The corresponding show that zone greater shallower source. In contrast, large-depth reception less affected.
