Patent number: 10422644Abstract: A method for improving target location accuracy in direction finding systems is disclosed. A target search region is identified based on a set of received signals, and the target search region is projected onto the earth's surface. An initial search grid, which is smaller than the target search region, is placed within the target search region. Next, the initial search grid is expanded to a full search grid by using an optimum number of virtual grid points in order to cover the entire target search region. The correlation coefficients at the virtual grid points between the estimated phases of emitted signals and the estimated phases of the received signals are then calculated. A target is designated as being at a location associated with the highest correlation coefficient. At this point, a new travel path can be initiated to engage or avoid the target.Type: GrantFiled: November 9, 2017Date of Patent: September 24, 2019Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Richard E.

Patent number: 6034647Abstract: An inverted boxhorn antenna array comprising a power divider that is constructed from a single metal piece and a flat metal sheet that is fastened to a rear surface of the power divider. The power divider is fabricated using a variety of waveguide junctions coupled between substantially identical inverted boxhorn subarrays. The junctions includes a central magic tee junction for coupling energy from an input port into the power divider. Alternating folded shunt and folded series tee junctions are used to transfer power coupled by way of the central series junction to the inverted boxhorn subarrays. Specially dimensioned folded shunt and series tee junctions are used in the inverted boxhorn subarrays. Waveguide matched loads are bonded in waveguides between each of the inverted boxhorn radiators of the subarrays. A fully functional antenna assembly includes a radome cover, a quadrature correction plate 18a, and a twist polarizer disposed in front of radiating elements of the inverted boxhorn antenna array.Type: GrantFiled: January 13, 1998Date of Patent: March 7, 2000Assignee: Raytheon CompanyInventors: Jeffrey A.

Patent number: 5786739Abstract: A waveguide evanescent mode filter is integrated with a monolithic microwave integrated circuit (MMIC) by forming both the MMIC circuitry and the waveguide filter on a single substrate that forms a common ground plane for both elements. The waveguide has a superstructure with an interior recess that is contoured to provide a desired cutoff frequency. The underlying portion of the ground plane can form the lower portion of the waveguide itself, and can also be contoured to define the cutoff frequency. Adjustable attenuation is provided by a resistive card that can be inserted by different amounts into the waveguide.Type: GrantFiled: September 3, 1996Date of Patent: July 28, 1998Assignee: Hughes ElectronicsInventors: Jeffrey A.

Patent number: 4215313Abstract: The specification describes a dielectric image guide harmonic pumped mixer circuit wherein two dielectric image guide strips of different chosen cross-sectional configurations are mounted on a metallic substrate which forms the image plane for the mixer circuit. These image guide strips have impedance matching tapered ends which extend into a central mixer cavity region on the substrate. A pair of reverse poled mixer diodes are mounted in the central cavity region to receive respectively RF incoming signals from one dielectric image guide and local oscillator signals from the other dielectric image guide. Differential currents generated in the two diodes cause the second harmonic of the local oscillator signal frequency to mix with the incoming RF signal frequency. An intermediate frequency (IF) signal current produced thereby is conductively coupled from the mixer cavity into IF signal processing electronics.Type: GrantFiled: May 31, 1979Date of Patent: July 29, 1980Assignee: Hughes Aircraft CompanyInventors: Yu-Wen Chang, Jeffrey A.

Patent number: 4172663Abstract: In an optical wavelength meter, the wavelength of light to be measured, such as that obtained from a CW or pulsed laser, is directed through a tunable grating monochromator, serving as a bandpass filter, for passing light within the selected bandpass and determining, to the lowest degree of resolution, the wavelength of the light to be measured. Thence, the light is directed sequentially through a plurality of Fabry-Perot etalon interferometers of increasing degree of resolution. The interference patterns are sequentially directed onto a spatial detector. The radii of the first and second rings of the respective interference patterns are measured to derive fractional fringe order measurements of successively higher resolution, such that the wavelength of the light to be measured is determined in successively increasing steps of higher resolution.Type: GrantFiled: April 27, 1977Date of Patent: October 30, 1979Assignee: Board of Trustees Leland Stanford Jr., UniversityInventors: Robert L.
