Abstract:

Design and evaluation of radio frequency RF systems that must operate through ionospheric disturbances resulting from high altitude nuclear detonations requires an accurate channel model. Such a model can be used to construct realizations of the received signal for use in digital simulations of transionospheric communications links and radars or for use in hardware channel simulators. This paper describes a general model which varies smoothly between the frozen-in and turbulent models. The starting point for the general model is a description of the electron density fluctuations in the ionosphere that includes space-time correlation. Then the mutual coherence function for the general model is presented. Examples are given which illustrate the effects on the received signal due to the variation from the turbulent to frozen-in models.
