Disclosed is a tracking device configured to estimate a track for at least one possible target and configured to receive incoming measurements and to process measurements and tracks, which tracking device is configured with a storage and a computational device having a computational capacity and configured with an association module configured to calculate an association between a measurement and a track. The tracking device further comprises an output module configured 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 set of active tracks and which track updates to add to a set of passive tracks. Computations on the set of passive tracks may be deferred until at least one passive track handling criterion is fulfilled; and the computational device may be configured to activate a passive track from the set of passive tracks and transfer the passive track from the set of passive tracks to the set of active tracks. |
