摘要： A Schwarzschild Antenna cooperates with an organ pipe scanner to achieve wide angle sectoral scanning of a high gain pencil beam. A rotatable mirror switches the antenna to conical scanning whereby microwave energy communicates between a nutating horn and reflectors of the Schwarzschild Antenna. During conical scanning, the organ pipe scanner remains unenergized. The mode of operation is selectable by the operator and the system is designed for rapid switching.

摘要： A quasi-spherical multi-reflector radar antenna has a subreflector and a main reflector with an aperture formed centrally therein. A mirror wheel is positioned behind the aperture while a fixed microwave energy beam is directed axially or radially against the wheel for subsequent reflection to the far field. As the mirror wheel rotates, the microwave energy reflected from the mirror wheel reflects at varying angles to effect unidirectional sector scanning of a high gain pencil or oval beam in the far field.

摘要： A Schwarzschild Antenna has main and subreflectors. A ring switch disposed behind the aperture in the main reflector generates a unidirectional sector scan beam that is collimated and transmitted to the far field, via the reflectors. The ring switch is comprised of two ring-shaped waveguide halves one of which rotates with respect to the other. Feed horns are mounted to one of the rings and are directed radially inwardly. Microwave energy from a transmitter is communicated to the horns, via the ring switch. Microwave energy emanating from the horns is directed by a lens to a rotatable mirror reflector that in turn reflects the resultant sector scan energy to the main and subreflectors of the antenna. The mirror reflector can be rapidly repositioned to allow the direct communication of a separately generated conical scan to the main and subreflectors of the antenna.

摘要： A Schwarzschild radar antenna has an organ-pipe scanner for producing relatively wide angle unidirectional sector scans of a high-gain pencil beam. When conical scanning is desired, energy from selected pipes of the organ-pipe scanner is directed to a nutating mirror that reflects the resulting conical scan to the reflectors of the antenna that reflect conical scan energy to the far field. A rotatable disc behind the main reflector controls the size of the aperture therein and provides decreased blockage when the antenna operates in the conical scanning mode.

摘要： A plurality of radial waveguides communicate microwave energy to respective circumferentially positioned horns. A stationary feed horn is disposed in the center of the waveguides to sequentially feed microwave energy to centrally located inlet openings in the waveguides. The waveguides rotate as a wheel while the circumferential horns generate a unidirectional sector scan beam. The scanner is installed in a Schwarzschild reflector system to provide a high gain, scanning, pencil beam in the far field. In addition, a conical scan mode is provided. A switchable mirror permits the operator to select either mode of operation.

摘要： A Schwarzschild Antenna includes feed horns respectively mounted on a turnstile waveguide switch. During transmission, as each horn passes a particular arc of rotation, microwave energy is emitted from the horn onto an adjacent mirror that reflects the energy to the antenna reflectors. The result is a unidirectional scan in the far field. A tracking mode of operation is also provided. Either of the two modes of operation may be selected by the operator.
