Study On Modeling And Simulation Technologies Of The Virtual Battlefield Electromagnetic Environment

Surface-to-air anti-radiation missile weapon system is an effective "hard killing" weapon in integrated electronic warfare. By using modern modeling and simulation technologies, virtual battlefield environment can be constructed for surface-to-air anti-radiation missile weapon system, combat application can be simulated, and combat effectiveness can be evaluated. This thesis studies critical modeling and simulation technologies to implement the virtual battlefield electromagnetic environment simulation system. The virtual battlefield electromagnetic environment simulation system is an important component of the surface-to-air anti-radiation missile weapon simulation system, and be mainly used to produce battle scenario and virtual battlefield electromagnetic environment for anti-radiation missile weapon simulation system.This thesis analyzes and studies primary radiant equipments in battlefield electromagnetic environment under the representative background of battle scenario, on this basis critical mathematics model of the virtual battlefield electromagnetic environment simulation system is established, critical technologies to implement the simulation system are studied, relevant simulation software system is researched and designed. The thesis consists of three sections:First, aiming at the representative background of battle scenario, the characteristic and working mode of primary radiant equipments in the battlefield electromagnetic environment is analyzed, critical mathematics model of the virtual battlefield electromagnetic environment simulation system is established, including Pulse Description Words model of radar equipments,jamming equipments,Tactical Air Navigation System(TACAN),Identification Friend or Foe(IFF),Joint Tactical Information Distribution System(JTIDS) and antenna pattern calculating model of radiant equipments on air motion platform.Secondly, three critical technologies involved in implementating the virtual battlefield electromagnetic environment simulation system are deeply studied. Possible representative battle scenario in important regions is analyzed and researched, design technologies of simulation system battle scenario is described in detail with the example of the battle scenario that double aircraft carrier battle groups assault land target from two directions. On the basis of mathematics model of radiant equipments that has been established, PDW simulation and implementing technologies of representative radiant equipments are studied. Technologies to implement target situation display based on MapX are elaborated in detail.Finally, the virtual battlefield electromagnetic environment simulation system software is developed basede on High Level Architecture (HLA) standards, which lays a foundation for the development of the whole surface-to-air anti-radiation missile weapon simulation system.
