Abstract
A method to initialize tracks from sensor measurements is provided. The method includes identifying at least one tentative track based on data collected from at least one sensor at three sequential times; initializing a confirm/delete track filter for the identified tentative tracks; and using gates computed from state vector statistics to one of: confirm the at least one tentative track; reprocess the at least one tentative track; or delete the at least one tentative track.
