Aiming At The Netted Radar Electronic Interfrence Technology Research

In response to the radar electronic jamming technology unceasing development, thesystem of the radar system and anti-jamming technology continues to progress. Theanti-jamming ability of netted radar is a kind of new radar system, because it haswidespread distribution of airspace, frequency, structure and polarization diversity andinformation fusion characteristics, which makes traditional interference lose efficacybecause in limited power, deceive signal targeted, etc. It is difficult to implementeffective electronic interference for netted radar.For single jammer which has power defect and false track failure problems in nettedradar, this thesis studies the distributed oppressive jamming, false track cheatingjamming and their composite interference, the simulation results show these three wayscan be effective interference to netted radar and decline its detection ability.This thesis fully studies the advantages of distributed jamming: flexible distribution,distance and power advantages, etc. And performance of typical oppressive interferencestyle, combined with the deployment of distributed jamming, by the simulationdistributed repressive can form any scenarios of netted radar detection blind area.As for traditional cheating interference failure problem, this thesis researches thefalse track of single radar interference, and then researches how to implement false trackfor netted radar deception interference, analysis the requirements to carried out falsetrack for the priori knowledge of networking radar and interference machine. Itproposes interference algorithm for the radar main lobe and side lobe of implement falsetrack, and verifies.Finally it proposes a composite interference algorithm with distributed oppressiveinterference and false track, the interference method combines with the advantages ofdistributed oppressive jamming and deception jamming, because of the distributedjammers distribution advantage it makes the implementation of the deception jammingmore convenient; because of cheating on type and distributed power advantage it makesthe radiation power of composite interference reduced greatly. Through the simulation,this method makes the ability of target detection in the radar network declined in a certain airspace, and the composite interference method reduces the power obviously.
