Abstract: A system for tracking objects. Objects such as aircraft, ground vehicles, or vessels may be sensed with various sensors, including an Integrated Broadcast Service (IBS) (220), an Advanced Field Artillery Tactical Data System (AFATDS) (225), a network (230) of airborne radar sensors, a network (235) of aircraft each reporting its own position, a Blue Force Tracker (BFT) (240), and a network (245) of ground-based mobile radar sensors. Data from each sensor or network of sensors may also be fed, via a display interface layer (250), to a display. A tracker which may be referred to as a coherent aggregator (120) receives input from sensors or other trackers and also from an operator. The operator monitors the display and provides input to the coherent aggregator (120) to assist the coherent aggregator (120) in inferring tracks from measurement reports. Multiple coherent aggregators, in communication with each other and loosely coupled, may be operated simultaneously.

Abstract: Methods and apparatus provide calibration of a system using a cable check configuration and a calibration test configuration. A short to ground reflects an injected signal to characterize a first signal path in the cable check configuration. Switch setting can then be adjusted to inject a signal that is coupled to an array element and received from a feed. The signal paths can be characterized to enable in-field calibration testing.

Abstract: A method of locating a weapon includes detecting a weapon firing event with an optical sensor, the detected weapon firing event indicative of a detected firing of the weapon and indicative of a detected time of the weapon firing event. The method also includes detecting a projectile fired from the weapon with a radar system. The method also includes calculating a state vector associated with the projectile detection. The method also includes identifying a location of the weapon by backtracking the state vector to the detected time of the weapon firing event time. The method also includes communicating the location of the weapon. A system that implements the method is also described.

Abstract: According to one embodiment of the present invention, determining the location of a target of interest includes determining a beacon location of the beacon. The beacon location is transmitted to a sensor. The sensor is operable to determine a sensor location of the sensor. The sensor is further operable to determine a target location of the target according to the beacon location and the sensor location. The target location is distinct from the beacon location.

Abstract: According to certain embodiments, merging records includes receiving a graph comprising nodes, each node representing a record of a first database. The following is performed for each record: associate a merge handler of a plurality of merge handlers to a record, each merge handler operable to apply merge rules to the record; identify one or more merge rules to apply to the record; and apply the identified merge rules to the record to merge the record in a second database.

Abstract: According to one embodiment, an airspace deconfliction system includes a deconfliction tool coupled to a data repository that stores records describing airspace objects, such as routes to be taken by an aircraft, airspace regions, and/or corridors. The deconfliction tool determines conflicts in the geographic location of the one airspace object with the geographic location of at least one of the other airspace objects.

Abstract: According to one embodiment, a method for generating code includes receiving a database file describing a database and a database schema. The database includes a plurality of database records. A metadata tag is received, the metadata tag describing a business relationship between two or more database records. The database file and the metadata tag are integrated to form a merged file. Using a computer system, the merged file is converted into code.

Abstract: A method for data stream identification includes receiving a data stream from a data source and executing a first transform on the data stream to determine if the data stream comprises a first characteristic associated with the first transform. The first transform is part of a transform tree comprising a plurality of transforms arranged in a hierarchy. The method includes executing one or more additional transforms to determine if the data stream comprises one or more additional characteristics associated with the one or more additional transforms and computing an efficiency level associated with the execution of each transform. The method also includes identifying a path through the transform tree wherein the computed efficiency level of each transform in the path is above a threshold value to determine characteristics of the data stream.
