Lightweight EHF satellites for augmentation of anti-jam communications

14th International Communication Satellite Systems Conference and Exhibit, 1992
In an evolutionary EHF anti-jam military satellite communications system, the fundamental service provided by a backbone space segment can be significantly augmented through the use of lightweight EHF satellites or secondary payloads. The use of small EHF satellites to provide this augmentation provides a great deal of flexibility in the deployment and
