Advanced Ballistic Model and Its Experimental Evaluation for Professional Simulation Systems

Abstract

Training of officers, soldiers, guards and security personnel as representatives of the state security system responsible for ensuring public safety is a complex and multifaceted process, especially in terms of use of firearms. This process should be conducted at each level of tasks, which include the level of intervention, tactic and strategic while taking into account practical experience gained during domestic and abroad operations. For the purposes of this study the models of ballistic simulation systems will refer only to the most important areas from the point of view of the realism of the training process conducted on the basis of simulation systems designed to support the training of officers and soldiers. Multimedia shooting ranges are simulation systems allowing firearms training. Each of the multimedia shooting systems consists of two parts: the real part and the virtual part. The real part consists of the shooter, firearm or replica firearm, the vision system which allows detection of bullet hits, a computer and a screen for projection of shooting targets. Virtual part consists of a generated by computer simulated virtual world with shooting targets. Virtual world generated by the computer is displayed on the screen by the projector. In the article the results of implementation of the ballistics equations in the physical engine is presented. The Implementation reproduces projectile motion in the atmosphere in a manner consistent with the data from the ballistic charts from ammunition manufacturers. In the article the mathematical model of projectile motion has been extended to a mathematical model of the atmosphere, in order to simulate the atmosphere parameters like temperature, density and pressure at the given time of flight of the projectile. The use of ballistics equations implemented in the physics engine of the multimedia shooting range will increase the realism of the shooting training. The implemented ballistic model will allow to conduct training on longer distances than allowed by a traditional indoor shooting range, due to a faithful reproduction of projectile’s behavior in the atmosphere. Traditional indoor shooting ranges can be converted into a multimedia shooting ranges, which increase training opportunities through the use of modern computer graphics.
