A Markov Model for HF Channel Availability in Central Australia.

Abstract

In this report, the extensive database of HF spectral surveillance and background noise measurements, recorded at Alice Springs in Central Australia as part of the Jindalee over-the-horizon radar project, is used to develop a model for HF channel availability. Parameters in a two dimensional cyclostationary Markov model are estimated for representative months of Jindalee data. The resulting model may he used for short-term forecasting of HF channel availability for radar and communications, and as the stalling point for a study into long-term trends in usage.
