  • Geodesic lens
    Patent number: 4114162
    Abstract: A geodesic lens parallel plate waveguide in the shape of a quarter-sphere is used to interconnect a linear array of transmitting/receiving elements and an array of coupling elements. Using this aerial component, scanned radio beams can be generated by a transmitting aerial if the array of coupling elements is commutatively actuated. Unused corners of the geodesic lens parallel plate waveguide may be omitted.
    Type: Grant

  • Radiators for microwave aerials
    Patent number: 4112431
    Abstract: A microwave radiator in the form of a parallel plate transmission system with an array of radiating slots in one plate is used to transmit scanning planar radio beams. The radiating structure is shaped to form part or the whole of a cylindroid. The array of slots may be on the convex or concave side of the radiator, which is preferably curved in the plane of the axis of the beam. Scanning through 360.degree. is possible with a full cylindroid radiator having the array of slots extending over all its convex surface.

  • Aircraft guidance system
    Patent number: 4017862
    Abstract: A ground installation for an aircraft landing system has an array of transmitting elements located on the arc of a circle. When the elements are activated sequentially either in one direction ("to") or the other ("fro"), a signal is transmitted which, when mixed with a reference signal, produces a wave train in the aircraft having varying beat frequency. Cross-correlating two wave trains, produced by consecutive to and fro excitations, to establish the time delay between them can be used to establish positional information for an aircraft.
