Abstract
Oblique sweep‐frequency ionospheric sounding experiments indicate that the propagation is affected by a horizontal variation of the electron density. To gain insight into the importance of these effects, ray‐tracing experiments were carried out. Examples show the influence of the horizontal variation of the electron density. Variations of the critical frequency as well as variations of the layer height are considered.
