Research On Simulation And Evaluation Technology Of Electronic Countermeasure Modeling

As an indispensable part of the whole simulation system,it is very important to establish the simulation model of Radar electronic jamming accurately and effectively.The simulation of electronic jamming modeling and its evaluation work has always been the focus of the electronic countermeasure simulation system which has not been given enough attention and has not been studied objectively.On this issue and for the purpose of the reliability evaluation of radar electronic jamming simulation,the VV&A process of the electronic jamming simulation and the reliability evaluation of the simulation model are studied from the perspective of signal characteristics rather than weapon effectiveness in this paper.In the first part,the VV&A process of the simulation of radar electronic jamming system modeling is constructed.The verification and verification methods of each module are briefly introduced,and the verification method of simulation model is introduced emphatically.The static data verification method and dynamic data verification method are discussed respectively for the different types of output data types.According to the characteristics of each type of data the principle of several commonly used verification methods and their concrete implementation steps are introduced respectively.The second part introd uces the simulation method of Gaussian white noise,and the mathematical model and simulation method of several typical radar jamming modes.According to the different forms of signal,the jamming modes are divided into the suppressing jamming and the deception jamming.According to the purpose of the two types of jamming and the characteristics of the jamming signal,the factors that affect the reliability of the simulation model are obtained.The hierarchical set of evaluation index of the two kinds of simulation models are constructed,and The appropriate model validation method is used to verify the low level evaluation indicators with the evaluation results are obtained.The third part uses the analytic hierarchy process(AHP)to evaluate the reliability of the simulation model comprehensively.The implementation steps of AHP are introduced in detail,and a method of comprehensive evaluation of the reliability of simulation model is proposed in combination with quantitative model verification method and AHP,and put the test statics used in the model verification instead of the traditional expert scoring results as the evaluation result of each index.Finally,taking the RF noise jamming simulation model as an example,according to the low-level evaluation index obtained earlier,the evaluation results of high layer indexes are obtained step by step,and the resuly of the reliability evaluation of the simulation model is obtained at last,the credibility of the simulation model is obtained.This paper is developed in the order of the VV&A process of the electronic jamming system.The previous chapters are the theoretical support and data preparation for the subsequent chapters,and the conclusion of the reliability of the simulation model is obtained in the last chapter.
