An Ambient HE Radio Mode Model.
Abstract
An approximate method for calculation of high frequency skywave radio propagation geometry is developed. The method is inexpensive in comparison to ray trace techniques yet capable of accounting for instantaneous local ionospheric conditions including tilt and off-great-circle propagation. It is thus appropriate for use in assessment of system response to nuclear effects on HF propagation, including alterations of mode geometry. Errors inherent in the approximations are shown to be small compared to errors caused by inaccuracies in ambient or disturbed ionospheric models. (Author)
