On-board Warning System About the Proximity of UAVs and other Objects on the Air

The low altitude and low speed during the takeoff and landing stages make the aircraft vulnerable for the collision with foreign objects. In addition to birds, small and extremely small unmanned aerial vehicles, which can rise to altitudes of up to 500 m and do not have collision avoidance systems, can take a threat for the aircraft, because they can be seen only visually. To detect Unmanned Aerial Vehicles at a distance sufficient for maneuver, it is advisable to use on-board systems of technical vision that can detect a small object on the trajectory of the aircraft. The analysis of the systems of technical vision showed the advantage of detecting Unmanned Aerial Vehicles and other objects in the air with the help of an infrared search and tracking system.
