摘　　要：侦察卫星地面应用系统仿真的目的,就是为了模拟控制数据的形成过程,以及有效载荷数据从接收、处理到按用户需要形成情报产品的流程,通过模拟系统的控制流和数据流,找出系统瓶颈并优化系统流程。通过讨论卫星侦察地面系统的组成和功能,分析系统工作原理,提出了将系统流程分成用户服务流程和数据接收处理流程两部分的思想。基于离散事件仿真软件Arena,设计并实现了卫星侦察地面系统的用户服务流程和数据接收处理流程。通过仿真结果分析,找出了系统瓶颈所在,提出了系统改进意见。The purpose of simulation for reconnaissance satellite ground segments is to simulate the formation process of control data and flow of payload data from receiving, processing to forming into information product. Through simulating the reconnaissance satellite ground segments, the control flow and data flow of the system can be simulated so that the bottleneck can be found and system flow be optimized. The paper discussed the composition and function of the reconnaissance satellite ground segments, analyzed its operational procedure. The paper proposed that the ce satellite ground segments can be divided into user service flow and data reception and process flow. Based on the discrete - event simulation software Arena, data reception and process flow was designed and implemented. a simulation system containing user service flow and The system bottleneck was found out through analysis of the output data, suggestions were put forward to improve the reconnaissance satellite ground segments.
