Research On Coordinated Attack Strategy Of Multi-Loitering Ammunition Based On Intelligent Algorithm

With the informatization and intelligent trend of future wars and the development of new concept ammunition,advanced ammunition represented by loitering ammunition has become the research focus in the ammunition research and development field worldwide.The integration of intelligent algorithms,virtual reality,Unmanned Aerial Vehicles and other technologies provides new insights and methods for the design of ammunition.Focusing on the coordinated attack strategy of loitering ammunition after acquiring battlefield situation and target information,this paper studied the evaluation of target threats and combat effectiveness of loitering ammunition as well as the allocation of targets in coordinated attack and the planning of attack track.Finally,this paper is to complete the validation of virtual visual simulation of combat and trajectory based on VR-Forces.The main contents are as follows:First,the battlefield situation was designed hypothetically according to the purpose of the study,and the loitering ammunition and target models of different types,models and performances were built.The flat terrain and complex terrain were identified according to the elevation data provided by VR-forces terrain database,and the terrain model was established to develop the basic battlefield model.Secondly,based on the battlefield situation information such as combat unit performance,ammunition-to-target position relationship and ammunition-to-target number relationship,a method of combat effectiveness analysis for loitering ammunition based on Entropy method and AHP Algorithm was proposed,the target threat coefficient was calculated,and the effectiveness evaluation of loitering ammunition was carried out.The cost function models of target assignment in different battlefield situations were constructed based on Assignment problem.Applying Discrete Binary Particle Swarm Optimization Algorithm(BPSO),the optimal target assignment scheme in the battlefield model was obtained by searching for the integrated combat efficiency.For the loitering ammunition that has clear attack targets,the algorithm was designed based on Ant Colony Optimization Algorithm(ACO)through the research on ant searching mode,heuristic function,fitness function,etc.,and the attack trajectory planning under flat and complex terrain was carried out.The influence of different parameters on algorithm performance was analysed.Finally,based on the virtual combat simulation platform-VR-forces,this paper demonstrated the entire attack process and validated the feasibility of loitering ammunition attacking track under the actual terrain.Based on the above research results,it can provide a reference for the coordinated attack decision of loitering ammunition.
