FIELD: physics.
SUBSTANCE: directional pattern zeroes are formed at angle of elevation of a radar beam which is not greater than the width of the directional pattern zero closest to the earth's surface, where one directional pattern zero is formed on each side of the main lobe of the directional pattern in the region of the closest side lobes on the elevation angle.
EFFECT: increased suppression of interference from sources with angular coordinates known beforehand.
