Abstract

The study is focused on numerical modeling of vertical ionograms in horizontally non-stratified ionosphere. We have considered the F2-layer ionospheric disturbance shifted horizontally from the sounding point. The presence of this kind of disturbance is related to off-vertical reflections and, hence, multipath propagation. We have investigated the ionogram additional trace that is formed due to off-vertical ray paths. Variations in the disturbance amplitude and related changes in the shape of additional trace have been considered. Typical ray paths are presented that form additional traces in the ionogram.
