  • Low cost parabolic cylindrical trough for concentrated solar power
    Patent number: 10488079
    Abstract: Reflectors for solar concentration and methods for formation thereof. A reflective assembly (1340) may include a plurality of elongate panels (370) forming a continuous trough (1330), and a frame (1230) configured to support the panels, with the frame with attached panels defining a parabolic contour on the top side of the trough.
    Type: Grant

  • Radar system with specialized weighting
    Patent number: 4117538
    Abstract: A radar system including an azimuthally scanned radar wherein the radar receives echo signals during each of a succession of azimuthally scanned directions of the radar receiving beam. Sequences of samples of data of received echo signals are stored with sets of samples relating to a common range being utilized for developing weighting factors for weighting received echo signals as a function of range. Thereby, dynamic fluctuations in signals strength because of clutter are reduced.

    Assignee: Raytheon Company
    Inventors: William W. Shrader, Ronald B. Campbell, Jr.
  • Digital MTI radar
    Patent number: 4015260
    Abstract: A digital MTI radar wherein, after an initial period, differences between the composite video signal of a present range sweep and a prediction of the composite video signal of such range sweep are digitized by an analog-to-digital converter.
    Type: Grant
    Filed: November 2, 1970
    Date of Patent: March 29, 1977
    Assignee: Raytheon Company
    Inventor: Ronald B. Campbell, Jr.
  • Focused laser doppler velocimeter
    Patent number: 3984686
    Abstract: A system for remotely measuring velocities present in discrete volumes of air in which a CO.sub.2 laser beam is focused by a telescope at such a volume, a focal volume, and within the focusable range, near field, of the telescope. The back scatter, or reflected light, principally from the focal volume, passes back through the telescope and is frequency compared with the original frequency of the laser, and the difference frequency or frequencies represent particle velocities in that focal volume.
