  • System and method of using image grids in detection of discrete objects
    Patent number: 8604969
    Abstract: A sensor is used to identify detections of discrete objects in a search grid. An image grid of the detections is created. The image grid is analyzed to identify a pattern of detections. The pattern of detections is used to identify objects of interest.
    Type: Grant
    Filed: April 5, 2010
    Date of Patent: December 10, 2013
    Assignee: Raytheon Company
    Inventors: Thomas E. Wood, Douglas W. Arent, Charles M. Ciany, Clifford M Curtis, Thomas B. Pederson
  • Active sonar system and active sonar method using a pulse sorting transform
    Patent number: 8400875
    Abstract: An active sonar system, a method associated therewith, and a computer-readable medium associate therewith, each provide a method of sonar signal processing. The method includes receiving a plurality of initial detections of a target and associated initial detection times, associated with sound transmitted at a pulse rate interval (PRI), and associated with received sound including echoes from a target. The echoes result from the transmitted sound. The method also includes analyzing the plurality of initial detection times with a pulse sorting transform configured to identify periodic PST detection times within the plurality of initial detection times that are equally spaced in time and that are representative of the echoes from the target.

  • Sonar system and method providing low probability of impact on marine mammals
    Patent number: 7486591
    Abstract: Low probability of marine mammal impact (LPMMI) sound signals have a modulation component selected to reduce a behavioral response from a marine mammal from that which would occur when transmitting another sound signal having approximately the same time duration component, approximately the same bandwidth component, and approximately the same center frequency component as the LPMMI waveform but having a modulation component comprising a frequency modulation.
