  • Short baseline helicopter positioning radar for low visibility using combined phased array and phase difference array receivers
    Patent number: 8493263
    Abstract: A helicopter position location system includes a receiver located substantially in a center of an array of receivers. A first array of receivers is located in a selected pattern separated from the center receiver by a first distance. Selected receivers in the first array are spaced apart from each other by at most one half wavelength of a base frequency of a locator signal transmitted from a helicopter. A second array of receivers is located in a selected pattern by a second distance larger than the first distance.
    Type: Grant

  • System and method for determining a position of a mobile device within a surveillance volume in the presence of multipath interference
    Patent number: 8077091
    Abstract: A system of determining a position of a mobile device within a surveillance volume includes a phase difference array comprising a spatially diverse array of N sensors for detecting RF signals from the mobile device and acquiring phase difference data from the RF signals, N being greater than 4. The system includes a processor for processing the phase difference data and determining the position of the mobile device from the phase difference data.
