With a view to detecting foliage-obscured/ground-obscured targets on a global scale, low
frequency (ie, very high frequency (VHF)/ultrahigh frequency (UHF) band) and wide …

In this paper, we present the derivation of the magnetoionic dispersion equation and the
corresponding index of refraction and propagation constant for characterizing wave …

Certain modern radio systems that rely on trans-ionospheric propagation require knowl
edge of changes in total electron content (TEC). Understanding rapidly changing, small …

This paper presents a fast and accurate algorithm for high-frequency trans-ionospheric path
length determination. The algorithm is merely based on the solution of the Eikonal equation …
