Track management technique for electronically scanned radars

A new method of track management for a phased array radar is proposed to simplify the data association and improve the allocation of radar resources. The tracks are organized into Association Groups and Dwell Groups. Association Groups are used for course gating when associating new measurement data with existing tracks, while Dwell Groups are used to efficiently schedule the next dwell on closely-spaced targets. By considering only closely-spaced tracks in the same Association Group, a form of coarse gating is inherently done to cull candidate tracks that are unlikely to associate with a measurement from a dwell to illuminate all of its members. A Dwell Group contains tracks that are spaced sufficiently to allow one dwell to illuminate all of its members. Dwell groups lay the foundation for more systematic approaches to optimal allocation of the radar resources. Simulation results are presented to illustrate the new technique.
