  • Patent number: 8681041
    Abstract: An angle-only tracking filter includes: a target angle discriminant unit configured to receive sensor signal outputs and form angle only observations of a target relative to an ownship; an ownship navigation filter configured to receive and filter ownship inertial navigation measurements; a model analyzer configured to receive and analyze the ownship inertial navigation measurements and select the order of target kinematics to be determined; and a target kinematics generator coupled to the angle discriminant unit, the navigation filter unit, and the model analyzation unit, including: a first-order filter unit configured to generate a target position from the target angle measurements and the ownship inertial navigation information; a second-order filter unit configured to generate a target velocity from the target angle measurements and the ownship inertial navigation information; and a third-order filter unit configured to generate a target acceleration from the target angle measurements and the ownship iner

  • Patent number: 8635622
    Abstract: In one or more embodiments, a method and system for scheduling resources is provided. The method includes receiving, in a processor, a plurality of concurrent processing requests. Each concurrent processing request is associated with at least one device configured to perform one or more different tasks at a given time. The at least one device has a predefined processing capacity. If one or more of the plurality of concurrent processing requests exceeds the predefined capacity of the at least one device at the given time, the processor determines a priority score for each concurrent processing request based, at least in part, on a time value associated with each concurrent processing request and whether any one of the concurrent processing requests is currently being processed at the given time. Responsive to the determined priority score at the given time, a highest priority processing request is executed for the at least one device.

  • Patent number: 8325082
    Abstract: A device and method for wide area surveillance of a geographic region includes identifying a search space associated with a geographic region having a plurality of sub-regions. The search space is divided into a plurality of search cells and observation data is collected for each of the plurality of search cells based on a scan of the geographic region. An event generation rate is calculated for each of the search cells based on the collected observation data. One or more of the sub-regions are identified as a region(s) of interest based on the calculated event generation rates. A coverage pattern is estimated for each of the sub-regions and a desired revisit rate is calculated for the region of interest based on the estimated coverage pattern. The desired revisit rate is then output for scanning the region of interest.
