Abstract:

Design and evaluation of Radio Frequency RF systems that must operate through ionospheric disturbances require 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 hardware channel simulators. This report describes the Fortran program ACIRF version 3.5 that generates realizations of the channel impulse response functions at the outputs of multiple antennas with arbitrary beamwidths, pointing angles, and relative positions. A general model that varies smoothly between the frozen-in and turbulent models is used for the temporal fluctuations of the impulse response functions. Examples are given which illustrate the effects on the received signal of the variation from the turbulent to frozen-in models, and the effects of antennas with arbitrary sizes and pointing angles. ACIRF inputs and outputs are described.
