Considerations for the Selection of Millimeter Frequency Bands for Mobile Satellite Communications

摘要

To provide communications for Naval forces at sea, a communications system must be mobile and must provide ocean coverage. At line-of-sight frequencies, the necessary coverage is provided by satellite relay. For practical and military reasons, mobile SATCOM terminals for the Navy must be limited in size, weight, and cost and must provide substantial resistance to jamming or unintentional interference along with a low probability that transmissons will be intercepted. It is primarily the military requirement for anti-jam (AJ) and low probability of intercept (LPI) performance in Naval SATCOM systems that dicates a need for millimeter wavelength systems where wide bandwidth transmission for AJ/LPI and narrow antenna beamwidths for LPI are possible along with the size and weight necessary in mobile terminals.
