Abstract: Unmanned aerial vehicles (UAVs) are increasingly being used in real-world applications, mostly military. This paper presents an efficient algorithm for path planning in guidance of autonomous UAV; generating stealthy paths through a set of enemy radar sites of known locations. A preliminary path consisting of a series of straight-line segments is first generated. Subsequently, the path is refined using a series of cubic splines in lieu of the straight line segments, resulting in a cost-effective path traceable by the UAVs. The shape of the trajectory is approximated using cubic B-splines. Simulated results are presented, illustrating the potential benefits of such algorithms.
