FIELD: radar equipment, air traffic control. SUBSTANCE: method involves provision of regions for intersection of flat beams of antenna beam pattern of at least two radars and movement of intersected regions during surveillance. When object which is bound to distance range of specific radar, is detected, its angular coordinates are represented by coordinates of common area of beam intersection region. Another claim of invention describes method in which signals of one radar are received by receiving channels of other radars. EFFECT: unambiguous measurement of elevation bearing and decreased size of interference region. 4 cl, 7 dwg
