Research On High Initial Velocity Kinetic Energy Weapon Under Future Airspace Window Block Firing Mode

With the development of high and new technology,in the modern war,the conventional artillery fired with the modern high-speed and high-maneuverability mobile aircraft,regardless of shooting accuracy or damage efficiency there were obvious deficiencies.High initial velocity kinetic energy weapons(Electromagnetic Gun as an Example)compared to conventional artillery have high initial velocity,high precision and high damage performance characteristics,it is one of the important development directions of future short-range air defense and anti-missile weapon.But the current electromagnetic gun is still in the early research stage,the damage performance of maneuvering target can not be calculated by live firing.In view of the above problems,this paper under the background of actual project demand,from the perspective of theory and simulation,studied and analyzed the feasibility of the method that shooting the maneuvering target in the future airspace window,with a view to provide technical reference for practical engineering design.The work and achievements of this paper are as follows:(1)Based on the conventional fire control trajectory theory,combined with the main features of the electromagnetic gun,a model of differential equations of external trajectory for the electromagnetic gun is established,and the influence of different factors on the external trajectory characteristics of the electromagnetic gun are simulated and analyzed.(2)Based on the standard IMM(Interacting Multiple Model)algorithm principle and the target motion model theory,aiming at the problem that the standard IMM algorithm is not sufficient for high speed and high maneuvering target tracking performance,a based on the adaptive Gaussian model and time-varying Markov transition probability matrix IMM algorithm is proposed.Firstly,an adaptive Gaussian model is used to improve the model set of IMM algorithm;Next,the current mode information included in the current measurement information of the system is utilized,and the Markov transition probabilistic setting is realized.The simulation results show that the improved algorithm has good tracking performance for maneuvering target.(3)Based on the mathematical description theory of traditional future airspace window,combined with the target state parameter estimation value and target air expectation damage region,an adaptive future airspace window firing model is proposed.First of all,according to the target to predict the future point coordinates and filter covariance matrix,the center point coordinates and the radius of the future airspace window are determined under the given confidence degree;Secondly,based on the characteristics of the high damage efficiency of the electromagnetic gun,the distribution center configuration criterion is optimized.The simulation results show that the adaptive future airspace window firing model not only effectively solves the problem of the supersaturation of projectile density in the traditional future airspace window spread center setting method,but also extends the block shooting damage area of the airspace window.(4)Based on the theory of adaptive future airspace window firing process and shooting error analysis,the calculating model of destroy probability is established and Monte Carlo method is used to simulate the damage probability of maneuvering target by weapon system.The calculated results validated the feasibility and effectiveness of the electromagnetic gun shooting of maneuvering target in the adaptive future airspace window.Through the above-mentioned research work,this paper from the theoretical analysis and simulation point of view,validated the feasibility of the electromagnetic gun shooting of'maneuvering target in the adaptive future airspace window,and it has certain reference significance for the electromagnetic gun practical application in the future.
