Abstract
A method and apparatus for analyzing newly acquired and faded or lost sonar contacts. Initial processing identifies a list of possible associations between a newly acquired contact and lost contacts. Subsequent processing of the possible associations reduces the number of possible associations that a sonar operator must consider in determining whether an acquired contact represents a new contact, a reacquired lost or faded contact.
