摘要
Apparatus for the detection and prevention of collision hazards between a ship fitted with a radar on board and moving or fixed obstacles identified on the radar screen on board of the ship, consists in determining with respect to said obstacles, taking into account such parameters as distance, speed and heading thereof, dangerous sectors of the heading and the speed for said ship, plotting said dangerous sectors for the heading and the speed on a support, plotting on the same support the speed vector of the ship, examining whether the end of said vector is within or outside said dangerous heading and speed sectors, a collision risk existing when the end of the speed vector is within at least one of said dangerous heading and speed sectors, and in such case, choosing a new speed vector so as to make the end of such vector be outside the whole of the heading and speed dangerous sectors.
