  • Systems and methods for carrier phase recovery
    Patent number: 9042490
    Abstract: Systems and methods for carrier phase recovery are provided. One method includes providing a reference signal, detecting an input signal and determining a Signal to Noise Ratio (SNR) of the input signal. The method also includes employing a Minimum Mean Square Error (MMSE) algorithm based on the SNR to determine a Carrier Phase Recovery Loop (CPRL) bandwidth.
    Type: Grant

  • Audio surveillance system
    Patent number: 8787114
    Abstract: A method and apparatus are provided for detecting objects of interest using sounds. Sounds are monitored for using a sensor array. A number of beams are formed. Each beam in the number of beams is formed for a selected direction in which the selected direction for each beam is relative to a line of sight for the sensor array. A presence of a number of objects of interest is identified using the number of beams and the sounds detected by the sensor array.

  • Beam-scanning system
    Patent number: 8451174
    Abstract: Technologies are described herein for locating and tracking objects of interest within a field of regard (FOR). Aspects include using a phased array to scan the FOR and receive signals emitted from an object of interest. The object of interest may then be located and tracked by processing the signals emitted from the object of interest.

  • Speed detector for moving vehicles
    Patent number: 8294595
    Abstract: A method and apparatus for detecting moving vehicles. A determination is made as to whether a number of vehicles are present in a video data stream received from a camera system. In response to the number of vehicles being present, a number of speed measurements for each vehicle in the number of vehicles are obtained from a radar system. A determination is made as to whether a speed of a set of vehicles in the number of vehicles exceeds a threshold. In response to a determination that the speed of the set of vehicles exceeds the threshold, a report is created for the set of the vehicles exceeding the threshold.
