Research On Jamming Planning Technology Of Cluster Jammers

With the development of modern radar networking,the operational effect of jamming system in single operation mode has been greatly weakened,which puts forward new requirements for the cluster development of jamming system.At present,the introduction of cluster system into electronic countermeasure operation is one of the main development trends of jamming system.This thesis focuses on the cluster jamming system planning under the fighter penetration scenario.In this scenario,the cluster jamming system composed of multiple jammers,which needs to assist the combat aircraft to perform the penetration mission.At this time,the planning effect of the jammer location,resource allocation and the penetration route of the mission aircraft in the cluster jamming system will determine whether the cluster system can successfully achieve the mission goal.However,at the present stage,the jamming system planning generally only carries out independent planning for the above planning objectives,and the combined jamming planning effect is difficult to achieve the best.Therefore,this thesis proposes joint optimization of multi-jamming planning objectives to improve the planning effect of cluster interference system.The research work of this thesis mainly includes the following parts:Firstly,the significance of jamming planning is introduced,and the change of the maximum detection range when radar is disturbed and the target of jamming planning for cluster system are discussed.According to the penetration model of radar network,the two-dimensional simulated battlefield environment is constructed.Based on the maximum operating range of enemy radar network,the operational target of cluster system and the kinetic energy of combat aircraft,the penetration battlefield model of radar network is constructed.Secondly,the joint planning of flight track and energy resource allocation of jammer is studied for the defense penetration system of fighter aircraft under the condition of selfdefense interference.The jamming benefit function of jammer is constructed,and the jamming planning model is constructed combined with the track distance of fighter.The particle swarm optimization algorithm is used to solve the jamming planning model,and the track planning of combat aircraft and the jamming power allocation planning results of jammer are obtained.Finally,the joint planning of flight track,space position of jammer and energy resource allocation of jammer is studied for fighter jet penetration cluster system supported by multiple jammer cluster.According to the distance between the jammer and the target radar and the power allocated by the jammer to the target radar,the risk coefficient function is constructed.Combined with the fighter track distance,the jamming planning model is constructed.The multi-objective particle swarm optimization algorithm is used to solve the model,and the Pareto optimal solution set with multiple interference schemes is obtained,and the typical cases are analyzed.The cluster jamming planning system proposed in this thesis realizes the joint planning of jammer energy resource allocation,jammer array and fighter track.The simulation practice proves the feasibility of the model and has certain engineering reference significance.
