Research On Implementation Method Of Jamming Effectiveness Evaluation And Calculation Software

The development of science and technology provides great support for the military field.As an important part of military war,the importance of radar countermeasure is beyond doubt.The operational level of radar depends on many indicators of jamming effectiveness,which has a significant impact on operational equipment and tactical command.How to evaluate the jamming effectiveness of radar efficiently and accurately has become the key to improve the countermeasure strength of radar.Aiming at the complexity of radar jamming mode,countermeasure scene,countermeasure organization mode,jamming effectiveness evaluation criteria and index system,this paper puts forward a new implementation method of jamming effectiveness evaluation software from the perspective of the research on the implementation method of computing software.The object-oriented abstract factory design pattern is used to construct the algorithm library of radar jamming effectiveness evaluation calculation model,the interface is defined in the abstract class,and the calculation model is implemented in the derived class,which unifies the interface and reduces the complexity of various jamming modes,modes and application scenarios in the evaluation process.The research content of this paper mainly includes the following aspects:(1)Firstly,starting from the basic concepts of radar countermeasure,effectiveness evaluation and abstract factory design mode,this paper clarifies its connotation,composition and characteristics,classifies radar jamming effectiveness evaluation according to radar countermeasure jamming mode,countermeasure scene,countermeasure organization mode,effectiveness evaluation criteria and evaluation indicators,and uses abstract factory design mode to define abstract classes.(2)Sort out the classified evaluation methods,and establish the evaluation model through the efficiency calculation method.This paper mainly constructs the efficiency evaluation model of repressive and deceptive interference,information,power,same risk criterion and interference signal ratio,minimum interference distance,detection probability,tracking error and miss distance.In different scenarios,radar jamming methods and evaluation methods are different,so the calculation model selected for jamming effectiveness evaluation is also different.The important concepts and elements of object-oriented technology are deeply combined with the calculation and evaluation method of radar jamming effectiveness.From the perspective of inheritance mechanism,polymorphism mechanism and object instantiation,the jamming effectiveness evaluation model is encapsulated and the effectiveness evaluation calculation algorithm library is established.(3)Use the data to verify the jamming effectiveness calculation algorithm library,and conduct experimental verification for different jamming modes and different evaluation indexes to judge whether the effectiveness evaluation method is effective.The evaluation of four different situations,such as the interference to signal ratio of suppression jamming and the traction distance of deceptive jamming,is effective.Therefore,the abstract factory design mode is selected to evaluate the radar jamming effectiveness,which can effectively evaluate the jamming in various situations,effectively reduce the complexity of radar jamming effectiveness evaluation,and evaluate the radar jamming effectiveness under different indexes,The effectiveness and practicability of the method are verified.
