A tracking device estimates a track for at least one possible target and is configured to receive incoming measurements and process measurements and tracks. The device has a storage device and a computational device and an association module to calculate an association between a measurement and a track. The device further has an output module to output a sequence of track updates from an assignment module maintaining a set of active tracks using the association module as a function of active tracks and the incoming measurements to calculate associations, containing possible track updates and deciding which track updates to keep in the active tracks set and which to add to a passive tracks set. Computations on the passive tracks may be deferred until at least one passive track handling criterion is fulfilled. The computational device may activate and transfer a passive track from the passive set to the active set. |
