Abstract A radar system comprises an antenna (2), which consists of a reflector (5) with two vertically mounted receiving elements (6, 7), and two receiving channels (3, 4) connected to the receiving elements. The receiving elements form, in cooperation with the reflector, practically coinciding cosecant-squared beam patterns. A measuring circuit (25), connected to the two receiving channels, measures the phase difference between the signals received in the receiving elements, which phase difference corresponds with the elevation angle of the target from which the signals were received.
