Abstract : The Regional Operations Control Center AWACS Digital Information Link/Rapidly Deployable Integrated Command and Control System (RADIL/RADIC) System Program Office, Canadian RADIL Progam, has acquired high-frequency (HF) radio equipment for two Canadian ground stations under the RADIL Project. This equipment will allow those stations to carry out Tactical Digital Information Link (TADIL) A data transmissions assisted by MIL-STD-188-141A automatic link establishment (ALE). The MITRE Corporation has been tasked to study whether U.S. TADIL stations should be equipped with similar HF-ALE modems. This report analyzes the improvements in performance over northern links that can be expected from the addition of ALE to the TADIL A system. Since there is only a small amount of data on ALE-assisted digital communications in northern regions, the analysis combines a probabilistic approach to comparison of ALE and conventional linking techniques with actual HF propagation data from links in Canada, Iceland, and Norway. The report also assesses the risks to effective communications of using an ALE-TADIL A system in the north and recommends several improvements in hardware and software that can lower those risks.
