  • Ground threat location for an aircraft
    Patent number: 8009515
    Abstract: Systems and methods are provided for locating threats to an aircraft that are located on the ground. Associated bearings are determined from an aircraft for each of a plurality of detected shots from a threat at ground level. A plurality of pairs of bearings are selected, and a weight value is calculated for each selected pair of bearings. An estimated position for the threat is determined from each selected pair of bearings. An improved estimation of the position for the threat is calculated as a weighted combination of the estimated positions.
    Type: Grant

    Date of Patent: August 30, 2011
    Assignee: Lockheed Martin Corporation
    Inventors: Joseph F. Cecala, Carl R. Herman, Stephen C. Moraites

  • Method and computer program product for identifying and incorporating new output classes in a pattern recognition system during system operation
    Patent number: 7164791
    Abstract: The present invention recites a method and computer program product for identifying one or more new pattern classes and incorporating the classes into a pattern recognition classifier as output classes. A plurality of input patterns determined not to be associated with any of a set of at least one represented output class by a pattern recognition classifier are rejected. The rejected pattern samples are then grouped into clusters according to the similarities between the pattern samples. Clusters that represent new pattern classes are identified via independent review. The classifier is then retrained to include the new pattern classes as output classes.
