Abstract:Abstract. This paper discusses signal intensity calculations for ionospheric HF radio waves using the geometrical optics approximation. To calculate the total signal intensity for an ionospheric channel, all the multipath and multimode amplitudes must be superimposed with their proper polarizations and phases. The basic method for calculating multipath interference with geometrical optics is presented. Using this method, the phenomenon of polarization fading is investigated and, in particular, the frequency-se… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
