Abstract

A procedure is considered for defining the presence of the tropospheric waveguide based on the shape of the phase-plane portrait, with which it is convenient to describe the behavior of all combinations of radio wave trajectories. A rough model of the spatial distribution of the troposphere refractive index n(x, z) near the sea coastline is given. The minimum information needed for model construction is from two separated vertical profiles of n(z) in the troposphere, which can be obtained by radio-acoustic sounding.
