Abstract
The propagation parameters obtained on four HF links in Northern Scandinavia have been obtained using the Damson Measurement System. Signals were transmitted on frequencies from 2 to 22 MHz and the SNR, multipath spread, number of modes, doppler spread and doppler shift were extracted. A detailed analysis of these propagation parameters has been undertaken in this study, and the characteristics of some of the Damson frequencies are presented in detail to provide a comprehensive overview of the properties of these high latitude HF links. Where appropriate, the predictions obtained from a high-latitude model are presented for comparison with the observed data. Data Communication over channels at these latitudes can be difficult, and low data rate robust waveforms are often required. The Damson data have been analysed to determine the range of conditions that must be considered when designing such a waveform.
