Cooperative jamming through the jamming of multiple jammers in the frequency domain,airspace,time domain,and working system,can effectively solve the problem of insufficient jamming resources or poor jamming effects of a single jammer,and also has absolute advantages in countering networking radar.So it plays an important role in the modern battlefield.According to the different working modes of radar,cooperative jamming can be divided into two types: coordinated noise jamming and cooperative deception jamming.In the process of implementing the cooperative jamming method,supplemented by an appropriate jamming strategy,the interference can be achieved with less effort.The cooperative jamming method and its jamming strategy are studied in this thesis.The main work of the thesis is as follows:(1)Researches on cooperative suppression jamming methods.The various combat use forms of cooperative noise jamming are summarized and combed,and an jamming evaluation index system for cooperative noise jamming is established.Blinking jamming and coordinated suppression jamming are the focus of research.The influence of various jamming parameters of blinking jamming on the jamming effect and the principle of parameter selection are analyzed.And the research and simulation experiments on the exposed area of cooperative suppression jamming are performed,which demonstrated the superiority of cooperative suppression jamming of small power jammers compared to the single jammer.And the method of station deployment when cooperative suppression jamming against low sidelobe radar is studied.(2)Research on cooperative deception jamming methods.The monopulse radar system and its vulnerable links are introduced.For the existing single-platform multisource reverse cross-eye interference,it is improved to be suitable for multi-platform cooperative multi-source reverse cross-eye interference in the context of multi-bomb cooperative penetration,which solved the problem that the existing cross-eye jamming equipment could not be applied to the small platform on the missile.Then the jamming scenario of the method is clarified,and a mathematical model is established.In addition,theoretical research and simulation analysis is performed on the cross eye gain and system parameter tolerance.And the advantages and disadvantages of the cooperative multi-source reverse cross-eye interference of linear array and circular array are compared.(3)The gray correlation degree algorithm is used to evaluate the radar threat level,and the jamming resources are tilted toward the more powerful radar.For different jamming methods,a corresponding coordinated jamming strategy allocation model and jamming resource allocation optimization index are proposed.The genetic algorithm(GA)and binary particle swarm optimization algorithm(BPSO)are used to solve the problem of interference resource allocation.The correctnesses of the model and optimization index are verified by simulation experiments,and the algorithm performance is compared.
