FIELD: the invention refers to radiolocation and may be used in two-coordinate radar stations of meter range with an antenna array consisting of two subarrays with phase centers spread along the height for measuring of the angular attitude of radar targets.
SUBSTANCE: the achievable technical result of the proposed invention is significant reduction of the number of ambiguities at definition of the angular attitude of the target in the radar set of meter range due to working on two-three frequencies. The indicated result is achieved due to measuring of relation of the amplitudes of the signals in the subarrays of the antenna according to which with taking into consideration the known form of the direction of the subarrays they define the set of possible values of the angular attitudes of the target on several frequencies and adopt as true value the angular attitude coinciding on all frequencies.
EFFECT: significant reduction of the number of ambiguities.
