Design And Simulation Of NMD System Based On HLA

With the development of ballistic missile technology, ballistic missiles is a major threat to the strategic and tactical objectives on the battlefield. The world’s power military want to breakthrough threat of missile in missile defense technology, so that missile defense technologies is paid attention to more and more countries. From the 1960 s, the United States began to develop Nike-Zeus anti-missile defense system, has been upgraded to a National Missile Defense(National Missile Defense, NMD) system, and the anti-missile technology is highest level in the world. The anti-missile defense system to develop in the direction of integration and network step by step. To carry out an in-depth research on Techniques in ballistic missile defense system, not only can provide technical support for China’s ballistic missile defense system, but also can provide important technical support, therefore, for the analysis and research of the missile defense system is an important military significance. Moreover, no matter from the protection of national interests are not violated or consider to eliminate the threat of an enemy of the state from the point of view, the ballistic missile defense system and research on the key technology involved are essential.Paper with the most advanced and perfect NMD system as the research object. Discuss the target after the intercontinental missile launch, NMD successful intercept the whole process of dynamic modeling. First of all, according to the high-level logical Architecture(High Level Architecture, the HLA) of the basic criteria and methods for NMD system of space-based infrared early warning satellites, early warning satellite ground stations, military communications satellite ground stations, military communications satellites, early warning radar ground station, ground-based radar ground stations, operational command and control centers, other components of the interceptor missile to establish the corresponding federal model. Secondly, combining with the actual interaction information between each component of NMD system, and detailed design the interaction between federal object. Interactive class is the interface of data exchange between the Federal. Finally, based on the information exchange relationship between the various functional units of the NMD system scenarios, construct the whole NMD system network topology, link up information transmission model for each unit. Due to the entire interception process involves multi-tasking, multi-platform, multi-load, multi-sensor system confrontation between simulations, this paper, by using distributed interactive simulation architecture implementation NMD complex system simulation.HLA distributed simulation system is applied NMD system, from an economic perspective, you can minimize the cost of defense spending; from the development cycle, greatly reducing the development and design cycles. Today simulation technology advances, the practice of the NMD system can rely on computer simulation technology, according to different environments and different sizes can be repeated confrontation simulation, testing weapons threat capabilities, operational program correctness verification. Do not need to spend a lot of manpower, weapons and other resources.The paper based on the idea of Dijkstra’s shortest path algorithm improvements, it can be applied to the regular satellite link routing algorithm, and the final simulation results are in agreement with the theoretical simulation.
