摘　　要：遥感卫星系统是远距离火力打击目标指示和战场态势感知的主要手段。首先,在分析遥感卫星系统运行流程基础上,针对侦察需求多优先级和系统能力有限性等实际情况,基于强占优先权排队模型提出了一种侦察时效定量分析方法;然后,分析了遥感卫星系统在战时和应急情况下的3种能力提升方法;最后,通过实例仿真,使用该方法对遥感卫星系统执行多样化侦察任务和进行能力提升时的时效性进行分析,验证了该方法的有效性,并给出了提升系统侦察时效的建议。The remote sensing satellite system is a main means of long-distance fire target indication and battlefield situation awareness.Firstly,on the basis of analyzing the operation process of remote sensing satellite system,and aimed at the actual situation of multi-priority reconnaissance requirement and limited system capabilities,a quantitative analysis method for reconnaissance timeliness is proposed based on preemption queuing model.Then,three capability enhancing methods for the remote sensing satellite system in wartime and in emergency are analyzed.Finally,with case simulation,the timeliness of the remote sensing satellite system on performing diversified reconnaissance tasks and im-proving its capabilities is analyzed.Thus,the effectiveness of the method is verified,and some suggestions to enhance the system reconnaissance timeliness is given.
