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.

Claims

1. A system for tracking a plurality of objects, comprising:

a data interface configured to receive a plurality of data elements, each data element selected from the group consisting of;

measurement reports comprising data about objects; and

tracks, comprising inferred trends in data about objects;

a user interface comprising a display and a user input device, the user interface coupled to the data interface and configured to display measurement reports and tracks; and

a first coherent aggregator, coupled to the data interface and to the user interface, the first coherent aggregator configured to;

receive at least one data element;

receive user input from the user input device;

generate a revised track in response to the data element and the user input; and

provide the revised track to the display.

2. The system of claim 1, wherein the data interface is configured to receive data from an Integrated Broadcast Service (IBS) sensor.

3. The system of claim 1, wherein the data interface is configured to receive data from an Advanced Field Artillery Tactical Data System (AFATDS) system.

4. The system of claim 1, wherein the data interface is configured to receive data from an airborne radar sensor.

5. The system of claim 1, wherein the data interface is configured to receive data from an aircraft transmitting its position.

6. The system of claim 1, wherein the data interface is configured to receive data from a Blue Force Tracker (BFT) system.

7. The system of claim 1, wherein the data interface is configured to receive data from a ground-based mobile radar sensor.

8. The system of claim 1, wherein the first coherent aggregator is a battle control system (BCS).

9. The system of claim 1, wherein the first coherent aggregator is an Enhanced-OASIS Fusion Capability (E-OFC) system.

10. The system of claim 1, wherein the user interface is configured to enable a user to designate two icons corresponding to two tracks to be merged into one track.

11. The system of claim 1, wherein the first coherent aggregator is configured to receive user input comprising instructions to merge two tracks into one track.

12. The system of claim 1, wherein the first coherent aggregator is configured to receive user input comprising instructions to interchange two tracks.

13. The system of claim 1, comprising a second coherent aggregator, loosely coupled to the first coherent aggregator, and configured to communicate with the first coherent aggregator.

14. A method for tracking a plurality of objects, comprising:

receiving a data element selected from the group consisting of;

measurement reports comprising data about objects; and

tracks, comprising inferred trends in data about objects;

receiving user input;

generating a revised track in response to the data element and the user input; and

providing the revised track to a display.

15. The method of claim 14, wherein the receiving of user input comprises:

displaying a plurality of tracks on the display;

enabling a user to select two tracks; and

enabling a user to provide, as user input, an instruction to merge the two selected tracks.

16. The method of claim 15, wherein the enabling of the user to select two tracks comprises enabling the user to left click on a first one of the two tracks and enabling a user to right click on a second one of the two tracks.

17. The method of claim 15, wherein the enabling of the user to select two tracks comprises enabling the user to drag a rectangle containing the two tracks.

18. The method of claim 14, comprising displaying information about an object of the plurality of objects.
