摘要
在兼顾网络容量和抗干扰性能的基础上,提出了一种卫星通信星状组网方案。介绍了抗干扰传输波形、网络结构和工作原理,对用户容量和抗干扰性能进行了理论计算。计算结果表明：直扩模式下单路转发器用户容量约360,跳频模式下单路转发器用户容量为120~400,并且具备较强抗干扰能力。相关组网方案对工程应用具有一定的参考价值。
A proposal for star topology satellite communication （ SATCOM ） network is designed based on tradeoff between network throughput and antijamming capability. The antijamming transmission wave-form, network structure, and operational principle are introduced and user capacity and antijamming capability are theoretically computed. The computed result shows that the user capacity for one channel tran-sponder is about 360 , and 120 ～140 at direct sequence spread spectrum （ DSSS ） mode and frequency hopping（ FH） mode respectively,and the proposal is of high anti-jamming capability. The networking pro-posal is valuable for engineering practice.
