RADAR METHOD FOR PREVENTING COLLISION OF AIRCRAFT WITH OBSTACLES IN VERTICAL PLANE AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2011 - IPC G01S13/93 

FIELD: physics.

SUBSTANCE: value of a signal which forms the width of the overlap zone of the directional pattern in the vertical plane is determined. The value of the signal which determines the range of angles of displacement of the directional pattern upwards and downwards is calculated. During antenna scanning in the vertical plane relative a stabilised position in the horizontal plane, the range signal for dangerous approach of the aircraft to the position of the object in the vertical plane relative the given altitude interval between flight levels in the overlap zone is determined, relative which a signal is generated in form of UP or DOWN marks when a dangerous object is found above or below the given altitude interval in the overlap zone. When a dangerous object is found in the overlap zone, UP and DOWN mark signals are generated simultaneously and when the dangerous object reaches the dangerous approach range, a collision prevention signal is generated.

EFFECT: high flight safety due to automatic flight control and preventing collision with objects in the vertical plane in a given flight altitude interval between flight levels.
