  • Coaxial cable connector
    Patent number: 4698028
    Abstract: A coaxial cable connector is provided, which resists radio-frequency breakdown in coaxial cables used in the vacuum of outer space. The connector body surrounds an insulator which includes an easily compressible elastomeric portion. An insulated coaxial cable is prepared so its insulation projects beyond the outer conductor and compresses the elastomeric portion of the connector insulator.

  • Method and apparatus for contour mapping using synthetic aperture radar
    Patent number: 4551724
    Abstract: By using two SAR antennas spaced a known distance, B, and oriented at substantially the same look angle to illuminate the same target area, pixel data from the two antennas may be compared in phase to determine a difference .DELTA..phi. from which a slant angle .theta. is determined for each pixel point from an equation .DELTA..phi.=(2.pi.B/.lambda.)sin(.theta.-.alpha.), where .lambda. is the radar wavelength and .alpha. is the roll angle of the aircraft. The height, h, of each pixel point from the aircraft is determined from the equation h=R cos .theta., and from the known altitude, a, of the aircraft above sea level, the altitude (elevation), a', of each point is determined from the difference a-h. This elevation data may be displayed with the SAR image by, for example, quantizing the elevation at increments of 100 feet starting at sea level, and color coding pixels of the same quantized elevation.

  • High power RF coaxial switch
    Patent number: 4187416
    Abstract: A coaxial switch capable of operating in a vacuum with high RF power in the 1.2 GHz range without "multipactor" breakdown, and without relying on pressurization with an inert gas, which requires a hermetic seal, is achieved by completely surrounding the RF carrying conductors of the switch with a high grade solid dielectric, thus eliminating any gaps in which electrons can accelerate.
