摘　　要：根据中继卫星资源使用特点设计了固定申请、柔性单窗口和柔性多窗口3种用户申请方式;针对3种申请方式采用Matlab软件编程分别模拟用户申请生成和资源分配过程,分析不同申请方式下中继卫星系统资源使用率与用户申请满足率、资源使用率与申请方式、申请粒度之间的关系,得出提高申请弹性和缩短任务时长均能有效提升申请满足率和资源使用率,中继资源使用率通常不要超过70%等结论。Three different application modes are designed according to TDRSS characteristics such as fixed single service time window mode,flexible single service time window mode and flexible multiple service time windows mode.Based on these three modes,a simulation model is constructed using Matlab to simulate user application generation and resource distribution process.This simulation modeling method is used to analyze the relationship between resource utilization rate and user application satisfaction rate,resource utilization rate and application method,and application granularity of TDRSS.It is concluded that increasing the flexibility of user application or reducing the time window of each application can effectively improve both the user application satisfaction rate and the resource utilization rate,and the TDRSS resource utilization rate should usually not exceed 70%.
