The Sniper Rifle Missile Trajectory Calculation And Sniper Simulation Training Research

Sniper rifle refers to rifle that choose from ordinary rifles or specially designed and manufactured. This kind of special rifle has high shooting precision, range and reliability. The main goals of sniper rifle in military is shooting the core targets(such as controllers, drivers,the gunner, etc.). It is the significant strategy for snipers to use sniper rifles against precision of the enemy targets.There are many factors that influence the snipers shot precision, such as wind direction,wind power, temperature, pressure, humidity, the shooting angle, moving ahead of target, the stable time goal of target and the technical ability of the gun. In the reality operation,observers need to observe and record the change of the external environment parameters, and according to their own experience and firing correction table to report to the sniper accurate firing correction information. Snipers according to the observers report information to adjust the target position, complete the firing. If snipers missed the target, the observer need to observe the bullet trail what can help the sniper readjust goals and position. In the sniper team training, snipers and observers need a close coordination and though a longtime communication to complete final shooting. Snipers need a long time hard training to become a dead shot.In the process of sniper training, the general experience according to the coach’s verbal,observations and observation of the effect of shooting that gradually adapt to the environment.This kind of training process is boring, not intuitive and has a longtime training. Generally to cultivate a good sniper take three to five years typically.In this paper, our purpose is to build a sniper training simulation system using the computer, through the method of visualization for sniper fire correction that provide an intuitive guidance. It can accumulate sniper shooting experience though different environments, therefore, the training period can be reduced and improve the training efficiency of snipers.This paper use USES MATLAB tools, combined with system simulation technology,detailed the external ballistics theory, the simulation technology of the main content and the basic theory of external ballistics. It provide a reliable theoretical basis and research methodsfor the next system.Secondly, this study also put the projectile in the vacuum environment, atmospheric environment, the natural non standard environment these three cases of trajectory mathematical model, and the calculation of deviation value to its corresponding algorithm is given. To simulate this model of projectile concentric and under certain initial conditions of ballistic trajectory is obtained by the experimental value of the yuan, it comparison with existing ballistic various values in the table, that produce the error that to prove the reliability of the system.At the same time, considering the main parameters affect of firing accuracy of calculated and according to the bullet ballistic parameters and impact, the angle of sight shows that current amount of deviation from different parts of the firing angle of shot on target.One of the biggest characteristic of this article is to suggest the aiming point is put forward, the sniper can change the actual aiming point though the suggest aiming point corresponding. So that to achieve the precision without adjusting the scale rapid purpose. Snipers in this training model can interactively adjust the shooting angle and the system will display the sight angle of deviation from different parts of the real-time that given shot on target. Snipers in the process of the adjustment can be visualized the result of the rapid correction experience to their shot.In live-fire training, snipers can use given aiming at guiding the sniper training simulation system, to improve the efficiency of training. At the same time,this paper aimed to achieve aiming quickly in actual combat and provide a new method of guidance precision.Finally, using the GUIDE in the MATLAB platform to build interactive user interface.Using this system could supply direct visualization result for coaches teaching and snipers to summarize the missile ballistic laws.
