Research On Hierarchical Electronic Countermeasures System Simulation

The traditional electronic countermeasure simulation system has satisfied the needs of model verification,data validation,tactical command and strategic planning to a certain extent.However,there are still some problems such as lack of functionality and compatibility,especially the support that the original system provided is weak in the re-organization simulation system.In this paper,hierarchical analysis method and hierarchical modeling method are studied,which can increase the efficiency of electronic countermeasure simulation system development and enrich the functions of simulation system,and give more help to further research and analyze.Firstly,it is tightly combined with the concepts of hierarchy and electronic countermeasure in this paper,the meaning of hierarchical electronic countermeasure system and the simulation factors in different levels are discussed.This paper takes the level division method for modeling and simulation of the US Department of Defense(Do D)in project management and organization as a reference combining with the actual connotation of electronic countermeasure system.In this paper the electronic countermeasures are analyzed in five dimensions,which are strategy,campaign,mission,engagement and engineering.Secondly,the hierarchical modeling method of electronic reconnaissance model is studied and a simulation example is built from the two levels as,engagement-level and engineeringlevel in this paper.Particularly two general organization methods of functional level simulation model of electronic reconnaissance model are discussed in this paper.Finally,the electronic jamming model is studied in the three levels,which are engineering-level,engagement-level and mission-level.The simulation results show that the modeling method proposed in this paper can solve the problem of hierarchical model construction,in particular,two general modeling methods for functional level simulation model are summarized in this paper,which meets the needs of simulation task and achieved good results.The results also show that the proposed mission planning algorithm is effective and efficient.The above research results provide a useful reference for the hierarchical electronic countermeasure system simulation.
