Research On Route Planning Method For Multi-UAVs Cooperative Complex Jamming

With the continuous development of information technology,the importance of unmanned aerial vehicle(UAV)in electronic warfare(EW)has become increasingly prominent.It can replace manned aerial vehicle to perform a variety of combat tasks in dangerous environments.Nowadays,because of the integrated air defense system with interconnection,intercommunication and data sharing,the jamming capability of single electronic warfare UAV is extremely limited.When multiple electronic warfare UAVs cooperate with each other to jam the enemy,the effect of expected jamming can be achieved.In addition,UAV route planning technology is the basis and key to realize autonomous flight,intelligent navigation and safe flight.Therefore,it is particularly important to study the route planning method of multiple UAVs cooperative complex jamming.Firstly,this thesis analyzed the operational application of electronic warfare UAVs.Introduce the structure and characteristics of UAV and describe the main tasks of electronic warfare UAVs.The operational application of electronic warfare UAVs in air attack is discussed,including feigned attack,cover jamming,distributed jamming and decoy jamming.And the development trend of electronic warfare UAVs is summarized.Then,this thesis studied the route planning method of multi-aircraft cooperative deception jamming.This method combines false target deception jamming with noise suppression jamming,which ensures the security of deception jamming UAVs and improves the reliability of false target track in the environment of radar networking.The optimal control model of UAV route planning with seven kinds of flight parameters constraints is deduced.Two different cost functions are proposed.It is considered that different cost functions can be flexibly chosen to plan UAV route in different situations.The flight route and corresponding motion parameters of all electronic warfare UAVs under two different cost functions are simulated with MATLAB.The results are compared and analyzed,and the validity of the route planning algorithm of multi-aircraft cooperative complex jamming is verified.Finally,this thesis studied the route planning problem of electronic warfare UAVs which are in jamming mission in multiple situations.Design a method of multiple electronic warfare UAVs cooperative jamming in cruising and searching phases for netted radar system.This method has practical significance and improves the security of electronic warfare UAVs in cruising and searching phases.In Cartesian coordinate system,propose the mathematical model of single aircraft deception jamming single early warning aircraft(EWA),the frequency formula and delay formula of the interference signal,which can deceive the enemy early warning aircraft and cover our warships.The method of multiple electronic warfare UAVs cooperative jamming multiple enemy EWAs is designed,and the corresponding optimal control model of UAV route planning is derived.The effectiveness of the jamming route planning method for all UAVs under the above three conditions is verified with MATLAB.
