Standing Wave Pattern of HF Radio Waves in the Ionospheric Reflection Region. Part 2. Applications

摘要

General analytical formulas derived within a uniform approximation are utilized for determining the wave pattern of a vertically propagating HF wave totally or partially reflected from the ionosphere. The full three-dimensional wave is calculated accurately, also at the reflection point. Parameter values are typical of ionospheric modification experiments as two sites are chosen. The influence of the geomagnetic field and collisions are properly taken into account but nonlinear and coupling effects are excluded. It is shown that the geomagnetic field affects the wave pattern strongly and leads to a very high swelling in the first wave maximum below the reflection point.
