  • Patent number: 9431997
    Abstract: An interfering signal canceller for cancelling an interfering signal component of an input signal includes a voltage sensor element disposed in a primary path and fed by the input signal, a coupler disposed in the primary path and fed by the voltage sensor element, a Hartley image-reject element disposed in an auxiliary path and fed by the input signal for converting the input signal to an intermediate or baseband frequency signal, a phase slope compensator disposed in the auxiliary path after the Hartley image-reject element to allow broadband phase adjustment of the interfering signal component of a converted input signal, and an inverse Hartley image-reject element disposed in the auxiliary path after the phase phase slope compensator to convert the passed the interfering signal component to the predetermined band of frequencies and having an output fed to the coupler.

  • Patent number: 8681047
    Abstract: A system and method for providing coherent sources for phased arrays are provided. One method includes providing a plurality of transceivers configured to transmit signals and defining an array of nodes. The method also includes providing a plurality of beacons at different frequencies to one of aim or focus phase coherent energy generated by the transmitted signals from the plurality of transceivers, wherein the phase coherent energy is transmitted at a direction and a frequency determined with phase conjugation and independent of the location of the plurality of beacons.
