Research On Cooperative Interception Of Air-to-air Missiles For Multiple Penetration Targets

As one of the main weapons in modern air warfare,air-to-air missile can be launched quickly by aircraft platform,with strong mobility and large attack area,and can be used for all-day operations at all altitudes,in all directions.In order to improve the penetration probability,penetration aircrafts also have certain maneuverability.This paper takes air-to-air missile as the research object,and carries out the research of guidance interception for penetration aircrafts with different maneuvering types.The concrete works consist of the following parts:Firstly,the guidance interception of an air-to-air missile to a maneuvering target is studied.For the air-to-air missile that can be launched over the shoulder,a compound guidance law based on PID is designed.The interception simulation of four typical maneuvering targets are carried out.Secondly,the cooperative guidance interception of multiple air-to-air missiles to a maneuvering target is studied,and the time cooperative guidance law is designed.Simulation shows that multiple air-to-air missiles successfully intercept the target simultaneously.Thirdly,this paper gives a deep study on the interception zone of an air-to-air missile,giving the calculation steps of interception zone before being launched,dynamic interception zone after being launched and dynamic non-escape interception zone after being launched.For satisfying the requirement of real-time performance,a fitting method of dynamic interception zone after being launched is proposed.The reliability of the algorithm is verified by numerical simulation.Lastly,The cooperative guidance interception of multiple air-to-air missiles to multiple maneuvering targets is studied.This paper gives out a cooperative interception strategy,including target type recognition based on decision tree algorithm,target threat evaluation based on fuzzy rule,and multi-target assignment based on particle swarm optimization algorithm.In order to reduce the possibility of maneuvering escape,the space cooperative guidance strategy is designed.The results show that this strategy can realize the cooperative interception of multiple targets.
