The Modeling And Simulation For Attack-defense Counterwork Of Missile Based On Simulink/HLA

Over the past decades, computer modeling and simulation technology have made a great advantage on different theories and methods, and have been widely applied to the missile weapon system design and manufacture. The benefits of computer simulation based on mathematieal models, partly or even completely instead of Physical models, are well understood:higher work effieieney, shorter developed cycle, lower cost and more safety. Therefore, this paper studies about the design of modeling and distributed visual simulation for attack-defense counterwork of missile.The paper first describes the theoretical basis of modeling the missile, including mathematical models of projectile motion, navigation, the steering gear and control system. Based on those Simulink models of attack and defense missiles are made, Simulink models are controlled by VC interface with the way of Matlab engine, while it adds the anti-missile interceptor model control module to the attack model which adopts machine orbit movement technology, not only verifies the penetration performance of the missile attack, but also verifies the ability to intercept the missile defense,the offense and defense truly realize.Then, it proposes a distributed visual simulation model based on STKX component. It uses the method of shared memory and event to empolder a S-Function module which solves the difficulty of getting the real time Simulink data between Simulink and RTI; the method of inserting the STKX component and API connection functions is applied, it completes the transfer functions of STK and the integration of STKX with RTI, it applies STK to distributed visualization simulation based on not starting the STK; it provides basic of numberical simulation and visual simulation for the distributed simulation system. It also completes the distributed part of the visual simulation system.Finally Missile Defense Simulation System's overall implementation is completed, the distributed simulation of missile attack and defense architecture is given, FOM / SOM table of simulation system is built, it expatiates federation members alternation relation of the simulation system.on the basis of HLA bus numerical and visual simulation are combined, it completes missile Combat Simulations and planar/three-dimensional simulation results according to campaign assume are given for further research laid the foundation compaction.
