Hla-based Distributed Virtual Target Test System Design And Technical Studies,

Research on Distributed Virtual Flight-test System can generate well development foreground and quite favorable economic performance for developing of tactical missile weapon in China Now. High Level Architecture (HLA) is a new technique developing from computer technique, network technique and simulation technique. It mainly intend to solve the interoperability and reusability problem of distributed simulation system, so that the period of project development can be shorten, and the cost of development and the risk of the project's failure can be decrease effectively. It has a wide application in military simulation. So the development of the distributed virtual Flight-test system under the HLA framework has great theoretic significance and practical value.Firstly, this dissertation introduces the relative content, and principle of high level architecture. Then it also discusses the development process of application system in accordance with criterion of HLA, and narrates in particular what to accomplish in every step of FDEEP, analyzes the way of the development of HLA federate. Finally, depending on a given background, we analyzes, a development process and way of flight-test system based on HLA, and discusses the relative technology during developing this system.According to the requirement analyzing of the flight-test system, this paper designs the system structure and logical frame, do research on how to implement the simulation on HLA, set up the federation conceptual model and the federation object model, and constructs the federate.Deeply discusses the key technology of distribute simulation system, designs the Simulation Algorithm of missile in the flight-test system, and discusses time synchronization technology and Data Filtering technology for this system.Establishes experimental Platform, and develops the distributed virtual Flight-test system prototype by using the serial and special development tools made by MAK company and model tools of Multigen Creator, it implements the major function of various simulation entities, solves the problem of space-time consistency, and shows real-time procedure of total experiment in two-dimension and three-dimension. Finally, this paper analyzes the performance about the system, and the system satisfies real-time requirement.HLA has been applies in flight-test system simulation for the first time, theprototype system indicates that the system frame is more expansible and realizable, and it is meaningful in other related fields.
