摘要
卫星跳波束技术可在空间、时间、频率和功率四个维度上进行资源分配,以其优越的灵活性、资源利用效率以及适应地面业务动态变化的能力,在高通量卫星系统中展现出良好的适用性。梳理了卫星跳波束资源分配算法,分析了现有分配算法的特点和不足,并以低轨卫星星座系统的场景和需求为着眼点,提出了跳波束技术应用于低轨卫星星座系统上的有意义的研究点。
The satellite beam hopping technology can allocate resources in four dimensions: space, time, frequency and power. With the superior flexibility, resource utilization and adaptability to the dynamicchanges of ground traffic, it shows good applicability in high-throughput satellite systems. In this paper, the satellite beam-hopping resource allocation algorithms are reviewed, the advantages and disadvantages of existing allocation algorithms are analyzed. According to scenarios and requirements of LEO satellite constellation systems, a meaningful research point of beam hopping technology suitable for LEO satellite constellation systems is presented.
