| 520 | 3 |a"The Doppler and Multipath SOunding Network (DAMSON) is a system developed by the Defence Research Agency, UK, and the Communications Research Centre to measure the propagation characteristics of high frequency (HF) radio channels. The system is installed in northern Scandinavia, providing a unique opportunity to study the properties of high-latitude ionospheric HF links. In this report, the DAMSON system is outlined and the geography of the transmitters and receivers is described. The DAMSON signals were transmitted on ten pre-assigned frequencies from 2 to 22 MHz, with a minute-long transmission every ten minutes on each frequency. The SNR, multipath spread, number of modes, Doppler spread and Doppler shift were extracted from data recorded between April and October 1995 on each of four high-latitude HF links. A detailed analysis of these propagation parameters has been undertaken in this study"--Abstract, page iii. |
