Multiple hypothesis tracking for a distributed multiple platform system

Methods have been developed to apply Multiple Hypothesis Tracking (MHT) to a distributed multiple platform system for tracking missile targets. The major issue that must be addressed is the requirement for a single integrated air picture (SIAP) to be maintained across the multiple platforms. Communication delays and failures mean that the platforms will, in general, form different MHT hypotheses with resultant different output tracks presented to the users. Thus, logic, described in this paper, has been developed to ensure that similar data association decisions will be made across the multiple platforms.
