fan beam — A fan shaped radar beam, broad in the vertical plane and narrow in the horizontal plane. A fan beam allows only the measurement of the azimuth angle. Typically, a fan beam in aircraft surveillance radar is 1° to 2° in azimuth and 20° to 40°, or… … Aviation dictionary
Fan-beam antenna — A fan beam antenna is a directional antenna producing a main beam having a narrow beamwidth in one dimension and a wider beamwidth in the other dimension. This pattern will be achieved by a truncated paraboloid reflector or a circular paraboloid… … Wikipedia
