Research On Modeling And Effectiveness Evaluation Of Early Warning Radar System Based On DoDAf And Petri Net

As the core detector of the ballistic missile defense system,the early warning radar system determines the success or failure of the system's defense and interception,and is a key part of the missile defense.Therefore,in-depth study of early warning radar system and establish the corresponding model can provide a good simulation support platform for our country to construct early warning radar system,and provide a reference for the construction of our country.This paper takes the United States' s missile defense system(MD)as an entry point,and combines the relevant projects of the Beijing Institute of Astronautical Engineering as the background,the research on the important role of early warning radar in missile defense is carried out.The main work of this paper can be summarized as follows:The first section is introduces the composition of the ballistic missile defense system,and focuses on analyzing the development status of the early warning radar system and its importance in the missile defense system.The second part is introduces the relevant tools and theories used in the modeling of early warning radar systems: Department of Defense Architecture Framework(DoDAF),Colored Petri Nets(CPN)and CPN Tools.The third part combines the operational mission and operational flow of the early warning radar system,establishes the Do DAF model of this paper,and finally uses the CPN model to carry out simulation-driven verification,which makes up for the inability of the DoDAF static model to perform dynamic behavior verification.The fourth part focuses on the complexity of large-scale Petri nets in the analysis of architecture.This paper adopts a structural analysis method based on CPN correlation matrix,converts the CPN model's correlation matrix into a special square matrix,and then calculates its eigenvalues.By analyzing the structure of the Petri net model by the nature of the eigenvalue,the analysis of the large Petri net model becomes simple and easy.Finally,this method is used to verify the correctness and rationality of the Petri net model established in this paper,which lays a foundation for the effectiveness evaluation of early warning radar system.In the fifth part,the qualitative analysis of early warning radar system effectiveness evaluation was conducted from both the scope of radar detection and anti-jamming of the network,and the relevant mathematical model was established.Finally,the effectiveness of the evaluation of the network radar was verified by simulation and some valuable conclusions were obtained.
