Abstract : A report on antenna development for long-range search and height-finding radar systems is presented. One satisfactory X-band model of the AN/SPS-2 (XDQ) antenna was built and evaluated. It consists of a symmetrically-cut paraboloidal reflector of elliptical contour fed by an array of ordinary horns of limited aperture.
