Study On Profile Display Model Of Air-to-air Missile Attack Zone

A large number of new technologies were used in air combat,and merely studying the performance parameters of weapons or missiles can no longer meet the actual requirements.Therefore,the research of air-to-air missile attack area and missile kill probability is of great significance.Studying the air-to-air missile attack zone and missile kill probability can provide important technical basis for pilots to make timely decisions in air combat.The main research contents of this article are as follows:(1)For the air-to-air missile attack zone model,the missile can only be launched when our aircraft and the target are in the same straight line.The parameter of off-axis angle of the missile was added to enable the missile to hit the target even when it is offset by a certain angle.First,the air-to-air missile attack zone model and the solution of the air-to-air missile attack zone model are studied;then the air-to-air missile attack zone model with the off-axis angle of the missile was studied.The experiment analyzed the range of air-to-air missile attack area when the off-axis angle of the missile is 0-30 degrees.(2)For the simulation of the three-dimensional attack zone of air-to-air missiles,the time dimension is added to study the simulation results of the four-dimensional attack zone of air-to-air missiles.The experiment analyzes the impact of the time on the attack zone by calculating the missile attack zone at four moments when the missile and the target encounter different altitudes.(3)The missile kill probability value is an important reference quantity for the air-to-air missile attack zone,aiming at the problem that the solution method of the hit probability model is not ideal enough,the hit probability calculation based on the compound Simpsonmethod is proposed.Firstly,the hit probability model is studied;then,the solution of the hit probability model is studied;Finally,the probability calculation based on rectangular method,compound trapezoid method,and compound Simpson method is studied,and the influence of some important parameters on the air-to-air hit probability is analyzed.Through experimental analysis,the compound Simpson method for calculating the hit probability model is superior to the rectangular method and the compound trapezoid method in speed and accuracy.It is an ideal method for calculating the hit probability.(4)Based on the above research,an air-to-air missile attack area and hit probability display system are designed and implemented.First,the five modules in the system are analyzed,and then the system module test is used to observe the change of the air-to-air missile attack zone range,the result and time of the missile kill probability value by resetting the parameters.The system experimental shows that the system has certain reliability.
