This report presents the findings developed as a result of a Navy- funded Independent Exploratory Development IED investigation. This investigation allowed the testing of a new processor-based communication technology created to improve high frequency HF communications. The new HF communication technology that was examined is called Automatic Link Establishment ALE and is in accordance with Federal Standard FED-STD 1045 and Military StandardMIL-STD 188-141A. This report does not provide a complete textbook treatment of this subject. What is presented is a discussion of aspects of the subject necessary for an understanding of the study findings and use of this technology on Navy combatant warships to meet general command, control, communications, intelligence C3I requirements. Because this report is unclassified, special C3I requirements that might be of interest in the use of non-FED-STD HF ALE techniques are not discussed. The first part of this report is an introductory technical discussion of various aspects of HF FED STD ALE. The last part addresses the test dat analysis and results. Test data were obtained by Naval Ocean Systems Center NOSC during a Navy-Only test phase performed in conjunction with Navy support of a FED-STD Over-The-Air testing. During the Navy-Only test, both NOSC San Diego and NOSC Hawaii were active as data collection test nodes, and they used the same ALEnetworkingprotection protocol and equipment as when they were part of the FED-STD test network. This report attempts to assess the new HF ALE capability that satisfies FED-STDs 1045, 1046, and 1049 requirements in terms of its strength and weaknesses for Navy communications.
