摘　　要：协同作战中需要高精度的时间同步将各站点在同一时间获得的信息融合,从而获得精确的敌方目标态势图来作出相应的对策。结合传统算法TPSN中的同步封包交换及FPST中的根节点动态选取,设计在无GPS授时状态下,协同作战系统中适用的时间同步算法及具体的同步方案。保证了同步网络的健壮性及伸缩性,其理论上可达到的同步精度符合协同作战的需求。Cooperative combating system needs high precision time synchronization to syncretize informations what each stations acquired at the same time. The accurate situation diagram of target is obtained to countermeasure. Combined with synchronous packet exchange in TPSN algorithm and root node dynamic selection in FPST algorithm, the suitable algorithm of time synchronization and practical steps for cooperative system without GPS timing are brought in this paper, haleness and retractility can be ensured. The theory of precision can satisfy requirments in cooperative combating system.
