Research On Simulation System Of Accuracy Analysis For Ballistic Missile Based On Real-Time HLA/RTI

The accuracy simulation has become an indispensable technical approach in modern missile weapon design, finalization, producing and the missile troops training process. In this thesis we introduced a technique plan of the design of simulation system of accuracy analysis for ballistic missile based on HLA/RTI, proposed a technical reference model of system architecture and analysised its modules.Firstly, we gave out a design plan of the Simulation System of Accuracy analysis for ballistic missile Based on HLA/RTI, introduced architecture and composing modules of the simulation system as well as the function demand and technical request of the modules. Then we introduced the Federation Development and Execute Process (FEDEP), and designed an all-purpose RTI interface component for federates.Secondly we analysised the demand of real-time performance of this simulation system, also we analysised the effect of the RTI key technology on real-time performance.We introduced some reseach word on improving RTI real-time performance, and analysed the disadvantages of several existed real-time RTI. At last we proposed a new real-time RTI architecture and tested its real-time performance.Thirdly we proceed mathematical modeling on the missile powered phase and post-boost movement, and set the format of the data file which produced by trajectory calculation to meet the request of simulation, also we analysed main factors effecting missile precision. After that we introduced the application of Monte Carlo method in accuracy analysis for ballistic missile, and proposed a new engineering method based on Bayes method for accuracy analysis.Finaly we explained how to implement the six modules which composed the simulation system in detail, and discussed the verification, validation, and accreditation (VV&A) of the simulation system. The research of this simulation system has important significance and application prospects.
