Description: Principles of construction of surface radio-location measuring device of corners of place (or heights of flight) of air aims are offered in the microwave range of radio waves. Such measuring device is used jointly with an impulsive two-co-ordinate radar station and works only on a reception. Aerial of the offered device consists of two megaphones, carried on a height and along the axis of aerial. Such aerial is located on a small height above earth, and scanning (or to rock) her on the corner of place is not required. Work of height-indicator is based on measurings of change of phases of signals in megaphones.
