用WSN建立数据链的主从弹协同作战模型

Leader-follower coordination combat model with WSN-oriented data link

结合无线传感器网络(wireless sensor network,WSN)技术特点,提出一种用WSN建立数据链的主从弹协同编队制导作战模型。论文给出了模型的组成,描述了模型中不同WSN节点的组网方式及网络拓扑,并描述了WSN网络建立及实现过程。推导了基于XX型号导弹的领弹-攻击弹模式协同编队制导律,并在此基础上仿真分析了不同WSN网络时延对不同期望编队距离下协同编队制导误差收敛性的影响。仿真结果表明,不同编队期望距离具有不同的WSN网络时延容忍度,且期望编队距离越小,时延容忍度越大;在不同的期望编队距离下,编队误差收敛性都随着时延的增加而变差;在网络时延容忍度范围内,期望编队距离越大,完成预期编队队形的速度越快。对时延容忍范围的仿真与分析可为实际战术数据链设计提供一定指导意义。

Combining with the technical characteristics of wireless sensor network （WSN）, a leader-follo- wer cooperating combat model with WSN-oriented data link is proposed. The block diagram of the proposed model is presented, the network mode and network topology of different WSN nodes are described, and the establishment and implementation process of the WSN is also given. Simulation and analysis are carried out to analyze the influence of different WSN network delay on different expected formation distance of the proposed model under the derivation guidance law of XX missile. Simulation results show that different expected formation distance has different time delay tolerance. The smaller the expected formation distance is, the greater the time delay tolerance will be. The convergence of the formation error becomes worse with the increase of time delay under different desired formation distance. In the time delay tolerance range of network delay, bigger expectation formation distance can complete the expected formation faster. Simulation and analysis of the time delay range has great guiding significance for the design of the actual tactical data link.
