Research on military communication satellite and the performance of its downlink

With development of space-flight technique,digital communication technique and information safety technique and so on,some military Great-Powers dispose many weapons in the space arbitrarily,consequently grasp the "space supremacy" which is the threat against the safety of some other country.The advantage,disadvantage and the function of the military communication satellite in modern war is introduced.Then the jamming performance data against the downlink of the military communication satellite is analyzed and simulated.
