Helmut-Schmidt-University / University of the Federal Armed Forces HamburgThe threat imposed by terrorist attacks is a major hazard for military installations, e.g. in Iraq and Afghanistan. The large amounts of rockets, artillery projectiles, and mortar grenades (RAM) that are available, pose serious threats to military forces. An important task for international research and development is to protect military installations and implement an accurate early warning system against RAM threats on conventional computer systems in out-of-area field camps.
This paper presents the most commonly used mathematical methods for determining the trajectory, caliber and type of a projectile based on the estimation of the ballistic coefficient. The algorithms are implemented on low-end computer systems used in military camps. A comparison between the methods gives information about error propagation and reliability of the system. In addition, simulation-based optimization processes are presented that enable iterative adjustment of predicted trajectories in real time. Combinations of these methods will be compared to increase the accuracy of simulation. A graphical user interface (GUI) is programmed to present the results. It allows for comparison between predicted and actual trajectories. Finally, different aspects and restrictions for measuring the quality of the results are discussed.
