Modeling evasion tactics of a fighter against missiles in three dimensions

Approximating the savior trajectory of a fighter under missile threat is aimed in this study. Like our previous work, this paper is a part of the ongoing academic project, the Visual End-Game Simulation. A realistic generic fighter model is used as the target of a missile that employs proportional navigation system. For a fighter in the cone of a missile seeker, finding the closest point of this cone and applying the suitable commands to evade out on that point is taken as the objective function. Taking into account both the state and control variable inequality constraints, the three-dimensional evasion trajectory is sought. Example trajectories and control histories are shown. Also, the horizontal-s maneuver, of which the optimally is already proven, is analyzed by applying predefined controls in order to compare to our solution.
