Research And Implementation Of The Simulation System Of Airborne Missile Attack

Airborne missile attack is a series of process that aircrafts use air-to-air missiles to locksome targets, do some preparations for some attacks, do some parameter analysis and do thefinal strike in the process of the competition for air carrier. In the process the pilot couldcomprehensively learn the current attack state through a variety of data real-time feedback,which can drive the aircraft to select the correct way. In the history of the development ofair-to-air missile, the first generation and second generation air-to-air missile existed only assecondary weapons for naval guns. When the third generation air-to-air missile came, theair-to-air missile had had the ability of the directional interception, independent remoteprecision in tracking and the long-range precision strike which laid the foundation of thedominance of the air-to-air missile in air combat. The paper did the research work on themissile attack in air combat simulation system from following several aspects:1. The paper do some researches on some basic theories of missile attack simulationsystem, related technologies and certain system structures. Through research, It determinedsome elements needed by the missile attack simulation system, including the altitude, speed,Mach, direction, target azimuth information, scan range, the missile launch parameters, etc. Atthe same time, it also summarized the control relationship between the display mode of theseelements and the control of the elements. Control relations included target azimuth displaycontrol, seeker lock target control, display control missile launch conditions, etc. The displaymode of the elements included the basic symbol display, the attack state display and missilelaunch condition, etc.; In the process of simulation. The display and control relationship ofthese elements are consistent with the real missile attack system to ensure the real simulationeffect.2. The paper did some researches on the target bearing simulation algorithm for missileattack simulation system and supplied the specific implementation process. Target azimuthinformation acquisition is the premise of the missile attack system. The missile seeker lockand missile launch conditions determine the important parameters such as relative Angledeviation of target, the target distance, are calculated here. Pilots could get some veryintuitive understandings for the position of the machine which is relative to the target t hrough the movement trend of showing movement of target bearing box. Due to the huge influence tothe relative target azimuth information of native gesture, it could be relatively complicated todescribe the movement of target trend. The paper did some ana lysis to the whole process oftarget bearing computation and data requirements. And the paper divided it into the basicmodel and dynamic model gradually. The paper reduced the time complexity of the programthrough optimizing the target azimuth Angle deviation algorithm. The paper also suppliedsome specific implementation details of the algorithm at the same time.3. The paper did some researches on the simulation system state simulation algorithm ofthe missile attack, and presented the concrete implementation process. First, it did the analysisto the environment and the parameter for the missile attack state, and determined the displaygraphics and related parameters needed for the missile attack. Then according to thecharacteristics of high maneuverability and strong real-time performance, it made somejudgments on the air combat, many factors influence the missile target, such as the targetdistance, open shut down airborne radar, missile and unlock. It divided missile attack stateinto fixed axis and attack state against state and off-axis servo state three attacks which weremade some specifications. Pilots can clearly grasp the missile current work situationaccording to the missile target azimuth data and information display and the missile. Based onit, Pilots could judge what attack can best strikes on targets with conversing the switch. Thepaper supplied the specific implementation details of three missile attack state model.4.The paper did some researches on the judgment models for missile launch conditionand gets some relevant parameters of missile launch through the experiment that is allowed.The judgment models for missile launch condition is the next step operation after the missileslocked some targets. It could do a series of judgment based on the carrier aircraft flight statusand target azimuth information. It could Tip the pilot again what conditions are allowed formissile launching operation. The paper did some descriptions on missile launch conditions,such as missiles maximum launch range, minimum distance and target distance rate based oninformation such as some conditions of missile launch. Based on a large number of detailedexperimental data, it got the fire control parameters. And finally, it acquired correspondingdata of judging the conditions of missile launch.To sum up, main target of this paper is to study and realize the operation of the missileattack simulation system and it is to do the analysis to the relationship between the systemstructure and control of the whole system. And some other main targets of this paper is tosolve some difficulties in the process of realizing the systems simulation.The paper is also to test some specific data parameters and use some advanced technology to do some optimizations to the whole system.
