Military communications - Review and survey

Attention is given to the Defense Communications System, which carries common user traffic for commands and controls in the U.S., Europe and the Pacific, as well as to common-user Tri-service Tactical communications and the Joint Tactical Information Distribution System. The trend toward all-digital satellite links is noted; digital circuits have the advantages of being compatible with large-scale integration technology, providing high message quality for reconstitution and relay over long distances, and allowing use of advanced cryptographic techniques. Portable transceivers with a frequency-hopping anti-jam mode are also considered.
