Research On Dynamic Network Modeling And Cooperative Guidance Method Of Multiple Missiles

The ability of missiles penetration being challenged with the development of missile defense system in the modern wars. The battlefield situation and state reconstruction timely is acquired at Network center by the attack of multi-missiles coordination. The task is fished by multi-missiles, which cannot be fished by single missile, because of that multi-missiles attack target through collaborative guided from different directions at the same time. So the research work of multi-missiles coordination attack has good military meaning. To solve the problem of multi missiles in formation coordination attack target in the operational environment, multi-missiles dynamic network and multi-missile coordination terminal guidance are researched. The following aspects are researched:1. The present situation of missile network model is analyzed, the dynamic network model of missile system is analyzed, and the missile network model include network fault model and survivable model are established with the method of network analysis based on graph theory, and missile is regarded as the network net. The connectivity of missile network communication topology is analyzed, the multi-missiles flight states are analyzed with the connectivity of missile network.2. The missile and target motion model are analyzed, and the single missile guidance law is analyzed. The result, that the more trajectory curved with the larger scale factor and the more trajectory straight with the smaller scale factor, is concluded, with the 2D trajectory numerical simulation result using fourth order the Runge-Kutta method. In order to solve the control problem of multi-missiles coordination, the disadvantages of traditional proportional navigation guidance method is analyzed, and the variable time is added to the traditional proportional navigation guidance method. The requirement of time consistency is satisfied with the result of the numerical simulation.3. Under the background of multi-missiles coordinated attack aircraft carrier, the missile coordination state is simulated with the incomplete connective missile network and restored connective missile network in the environment of missile network. The collaborative consistency of restored connective missile network is verified. The six missiles coordinate terminal guidance is simulated based on both connective missile networks. The results show that missiles fail to meet the requirements of collaborative time under the incomplete network. The missile angle is consistency looking from the simulation result, the distance between missile and target is decreased, and the time between expected guidance time and actual guidance time is decreased. The effectiveness and feasibility of the missile coordinate guidance control method is verified by the numerical simulative result.
