Research On Compound Jamming Method Based On Track Deception

Radar active jamming aims to reduce the success rate of the radar party in obtaining stable tracks and protect the safety of the jamming party in complex electronic countermeasures environments.Therefore,as a part of electronic warfare,the radar active jamming technology used to achieve track deception is crucial.Modern radar has been able to adaptively allocate resources and significantly improve its anti-jamming performance.The main development trend of active composite jamming in radar today is the traditional additive combination of multiple jamming.Although its track deception effect has been improved,it is less likely to optimize the jamming effect or jamming resource cost through adaptive methods.Therefore,implementing traditional active composite jamming is no longer sufficient to ensure stable and effective track deception effects.An adaptive active composite jamming is designed to realize the adaptive adjustment of jamming parameters among composite jamming members,which can effectively improve the success rate of track deception and optimize the allocative efficiency of jamming resources.This article is based on the radar echo processing mechanism and the principle of radar active jamming,and focuses on the adaptive generation method of track deception composite jamming by combining different active jamming with range gate drag jamming.The main content of the article is as follows:1.Introduce the main workflow of radar signal processing and radar target tracking;Several typical radar active jamming methods are introduced based on the classification of radar active jamming,and the mathematical models and applicable scenarios of each jamming method are analyzed;Analyzed the advantages of different radar active jamming in the application of composite jamming,laying the foundation for the research of radar active composite jamming based on track deception in adversarial scenarios.2.Selecting noise product jamming and range gate drag jamming to design composite jamming,aiming at the problem of limited radar suppression jamming resources,this paper studies an adaptive track deception composite jamming generation method based on noise product under limited power,reasonably allocating jamming resources,and increasing the success rate of track deception jamming.3.Selecting intermittent sampling and forwarding jamming and range gate drag jamming to design composite jamming,based on the characteristics of intermittent sampling and forwarding jamming that can form suppression or deception jamming effects in different situations,adaptive track deception composite jamming generation methods based on intermittent sampling and forwarding suppression and multiple false target deception were studied and implemented.Both composite jamming methods have achieved improvements in towing distance and jamming success rate.The above methods have all passed simulation experiments and verified their effectiveness.
