  • Radar reflector
    Patent number: 5343202
    Abstract: Radar reflector structure is disclosed including a plurality of reflector elements which in use are arranged in a non-planar configuration, the reflector elements include a thin flexible member extending between adjacent reflector elements substantially at or below the surface of the elements, the thin flexible member thereby providing a flexible hinge between the elements.
    Type: Grant

    Date of Patent: August 30, 1994
    Assignee: GEC Marconi Limited
    Inventor: Stephen W. Bell
  • Military aircraft
    Patent number: 5150122
    Abstract: An aircraft (1) includes a radar reflector (2) arranged so that the radar signature of the combination of aircraft (1) and reflector (2) is different from that of the aircraft (1) alone. This confuses enemy radar either by removing or folding flat the reflector (2) when on a combat mission so that the aircraft (1) on its own has a surprisingly low radar cross-section; or, alternatively by making radar signature of the combination correspond to that of an aircraft of a potential enemy.

  • Deployment of radar reflectors
    Patent number: 5061929
    Abstract: A deployment system for a radar reflector comprises an outer shell (7) and a radar reflector (8). The radar reflector structure is contained within the outer shell (7) in a first substantially planar configuration. The radar reflector structure (8) is subsequently released from the outer shell (7) and adopts a second non-planar configuration.In one example, the outer shell (7) forms part of the fin (2) of a missile.In a second example, the outer shell (7) is a disc-shaped projectile suitable for launching from the deck of a ship.

  • Radar reflector
    Patent number: 4823131
    Abstract: A radar reflector (4, 5) comprises a hollow, generally spherical or conical radar transmitting housing (6) containing a radar reflecting assembly (10) having a number of trihedral cube corner reflecting elements arranged in strings one above the other and with a number of the strings arranged side-by-side around the inside of the housing (6). The radar reflecting assembly (10) may comprise strings of reflecting elements with the origins of all of the reflecting elements lying on and being arranged around a frusto-conical surface and with all of the reflecting elements facing outwards. Preferably, the radar reflecting assembly (10) comprises at least three strings of single or double-handed helical reflecting element arrays (20) arranged side-by-side.
