An organ-pipe scanner is a system used in some radar systems to provide scanning in azimuth or elevation without moving the antenna. It consists of a series of waveguides and feed horns arranged in front of a shaped reflector, each one positioned to reflect the beam in a different direction. The wave guides meet at a central point where a small rotating waveguide feeds the microwave signal into each of the horns in turn as it rotates past them. A similar concept is the Foster scanner, which is typically found on lower-power systems like counter-battery radars.
