With The Team Support Jamming Effect Analysis

As the important part of active jamming,ESJ is applied more and more widely.ESJ is a kind of tactics application,and some technology challenges are brought in the effect evaluation,such as ESJ’object characteristic response of dense formation and inflience of ESJ on radar detecting capability.Besides,which method we can take to get the best jamming efficiency on the condition of restricted load and how we can utilize the finite experimentation data to evaluate the ESJ are both problems,when we analyze the ESJ effect.Aim at above problems,targeting the influence factor of ESJ effect analysis,this thesis does the innovative and exploratory research on the formation object characteristic,typical jamming technology and evaluation method under ESJ background.The main content is as follow:1.On the basis of the typical formation mode of ESJ,the receiver response distributing of formation object synthesis under the condition of ESJ is derived.The distributing law and RCS fluctuation is emulates,which provides evidence for object RCS calculation,and the influence of echo signal on the radar system capability is analyzed.2.The typical jamming technology of ESJ is analysed and a high efficient formation method of dense false targets based on sampling superposition is put forward,Also,the jamming signal model is bulit and the jamming signal response is emulated,which provides the basis for jamming power calculation.The characteristic in application to ESJis analyzed.3.On the conditon of ESJ,the jamming effect of jammer on radar in different scheme is emulated and calculated on function hierarchy.The jamming sheltered region is discussed and the formation mode and characteristic are determined.4.SVM is introduced into ESJ effect evaluation.The response model is built.Then the evaluation experimentation of jamming effect is done and the model is proved effective.
