beam hopping

beam hopping
跳波束
Communication systems on modern satellites and other wireless communication platforms often employ a large number of narrow spot energy beams for communicating radio frequency (RF) signals. The narrower the spot beam, the smaller the user's antenna can be for a given bit rate, or data speed, to be effectively communicated. In a typical such communication system, the wireless communication platform has fewer communication paths (each path corresponding to a transponder) than the number of spot beams, and therefore the paths are time-shared. This time-sharing goes by the name of beam hopping, since conceptually a limited number of active beams are hopping around to serve a larger number of cells. A switch network typically performs the hopping function, selecting a communication path (or no communication path) for each cell, with the selections changing rapidly as the beams hop.
数字波束形成 (DBF) 技术大大地提高了军事通信系统的性能，然而，如果在通信波束的方向上受到强方向性干扰，这种干扰将严重地影响通信的质量。为此，本文提出了一种新的基于跳波束 (BH) 的军事通信方式。[...] 能够在充分地利用通信双方的波束方向性增益的同时，有效地对抗强方向性干扰，并具有一定的抗截获能力，是一种性价比较高的军事通信方式。
