【摘要】 随着卫星数目的快速增长,在有限的频率资源内,卫星系统之间需要实现频率共用。针对卫星频率共用存在的干扰问题,文中根据目前卫星可用频率资源,分析了频率共用形势,仿真卫星空间关系,得出地球站最小观测角,并全面分析了卫星典型链路的干扰模型,给出链路干扰分析方法,提出了频率共用的兼容性措施。更多还原

【Abstract】 With the rapid development of satellite numbers,satellite systems need to realize frequency sharing in the limited frequency resource.There are potential interferences due to frequency sharing.This paper introduces the frequency resource of satellite system,simulates satellite space relationship,analyses interference models of satellite typical links,puts forward the calculation means of electromagnetic interference,gives some frequency sharing measures based on EMC.更多还原
