Research On The Fusion Display Model Of Dual-aircraft Cooperative Air-to-air Missile Attack Area

In current air combat,dual-air combat has become a trend.Air-to-air missiles are the most used weapons in air combat.By calculating the attack area and hit probability,the performance of air-to-air missiles can be effectively judged.The research on the fusion display model of missile attack zone has important research significance.In this paper,the parameters of a certain air-to-air missile and carrier aircraft are used as research data to study and analyze from the attack area and hit probability.The main research contents of this article are as follows:(1)Aiming at dual-air combat,in order to meet the future trend of air combat,the dual-air-to-air missile attack area can analyze the attack range of the dual-air-air cooperative air-to-air missile under certain circumstances,and establish a dual-air-to-air missile attack area model.First of all,the three-degree-of-freedom model,the dual-machine motion model,the relative motion model and the guidance law model of the air-to-air missile are established respectively.Then,the coordinated dichotomy method is used to search the attack zone boundary range to obtain the near-far attack zone range boundary under the dual-machine condition.The Runge-Kutta method calculates the missile trajectory to determine whether the hit condition is met;finally,the boundary of the attack zone that meets the condition is calculated.The experimental results show that the attack area of the dual-air-to-air missile improves the strike range compared to the single-air combat.This model can provide a reasonable and effective method for the research in actual air combat.(2)The hit probability of dual aircraft air-to-air missiles has an important influence on the pilot’s launch decision.To solve the problem of how to reasonably calculate the probability of hitting two aircraft,establish a method and model for calculating the probability of hit of two aircraft based on azimuth weights.The probability of hitting the same target by both computers is calculated.Firstly,considering the azimuth angle between the two-machine movement direction and the target movement direction,a relative position model of hit probability based on azimuth weights is established;then three adaptive model-based calculation methods of hit probability based on azimuth weights are proposed;The results of applying different calculation methods under different relative position models are presented.Experimental results show that the proposed relative position model and algorithm can meet the needs of practical research problems.(3)On the basis of the above two studies,a dual-air-to-air missile attack zone model and hit probability display platform are designed and implemented.Under this platform,the dual-air-to-air missile attack zone and hit probability can be calculated through preset parameters.The main function is to solve the attack zone and hit probability,and display the attack zone.The system experiment results show that the model constructed in this paper shows that the system has certain reliability and stability.
