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.
