A method for automatic group tracking detects target formations and group tracks corresponding to each formation. Pseudo-observations are formed to represent missing observations in each track group. The pseudo-observations update the track states of undetected targets. Track validity estimates eliminate false tracks resulting from series of pseudo-observations. A group average velocity applied to each track in the group helps to maintain velocity stability. The operator has the option of suppressing the display of all tracks except for the leader of each group to eliminate the distraction of intra-group switching. This method can be applied to trackers that maintain a single track for each target or to trackers that maintain multiple track branches on each target, such as MHT.

[ What is claimed is:] [4.] A method for tracking targets traveling in groups, comprising a sequence of the following steps:receiving observations of the targets being tracked over time;associating current observations with corresponding target tracks each having a track state, a track state including position and velocity estimates for the corresponding target;assigning tracks in close proximity and with similar velocities to a track group;calculating an average velocity for the track group; andapplying the calculated average velocity to each track in the group by changing the velocity associated with each track in the group to the group velocity to provide track velocity stability.
