  • Winds aloft estimation through radar observation of aircraft
    Patent number: 5051750
    Abstract: A method and a system for determining the wind velocity vector in a region in which a turn is being executed by an aircraft using a positional detection system to obtain aircraft positional data during the turn, calculating the ground speed vector of the aircraft at a plurality of points during the turn and determining the wind vector that best fits the ground speed vector data. The wind velocity vector can be calculated even when the aircraft airspeed vector is not constant.
