Aiming at the problems of real-time and accuracy of the air-to-air missile attack zone calculation method and the two-aircraft cooperative combat method in the related research,as well as the need to focus on the study of the attack zone overlap area,this article establishes the attack zone solution method.On the premise of the simulation of the dual-machine cooperative attack area,the research on the overlapping area display model of the dual-machine cooperative attack area is focused on.The hit probability of the overlapping area and the size of the attack area are simulated and analyzed according to the target occupation.Based on the simulation of the overlapping area of the two-aircraft cooperative attack zone and the study of the hit probability,the three-dimensional simulation study of the missile trajectory and the four-dimensional attackable area with increased time dimension are conducted according to the three-dimensional proportional guidance law.The main research contents of this article are as follows:(1)Aiming at the real-time and accuracy requirements of the attack zone calculation method,an air-to-air missile attack zone calculation method based on the Sec search algorithm is proposed.The missile and target models are studied according to the factors affecting the delay of the steering gear and the different atmospheric resistances at different altitudes.Sec search algorithm is compared with the classic dichotomy method on the near and far boundary search iteration times,operation time and attack area simulation experiments under different potential heights.The simulation results show that the Sec search algorithm is more superior.(2)According to the requirement of the overlapping area research,the model of the attack area and the overlapping area model of the two-aircraft cooperative operation are established according to the model of the single aircraft attack area and the azimuth angle of the target relative to the carrier aircraft.According to the different azimuths of the missile's aiming,the hit probability of the overlapping area is studied.The missile's aiming azimuth is weighted to the hit probability.Through the simulation experiment of the overlapping area hit probability,it is found that the two-aircraft missile's aiming angle is smaller and the overlapping area hit probability is higher.(3)Display and study the overlapping area of the coordinated attack area of the target in different motion states,and calculate the attack area according to the simulation process of the two-aircraft coordinated attack area.According to the target's uniform straight-line motion in the horizontal plane,equal-speed turning motion in the horizontal plane such as overload and vertical planes in the overload climbing motion state,a simulation experiment is carried out on the two-aircraft cooperative attack area and its overlapping area.The aircraft coordinated attack area and its overlapping area have an impact.(4)Based on the above research,under the control of the three-dimensional proportional guidance law,the ballistic simulation and the four-dimensional attackable area display are studied.According to the simulation of the overlapping area of the coordinated attack zone and the study of the probability model,the missile trajectory of the dual aircraft is simulated.By changing the entry angle of the target,the influence on the trajectory of the missile and the target and the selection of the attacking bomb are studied.On the basis of three-dimensional space,the time dimension is added to obtain a visual display of the dual-aircraft cooperative four-dimensional attack zone with the time interval as the step size,so as to improve the reliability and accuracy of the combat mission.
