Joint Surveillance System Distributed Tracker

摘要

The Joint Surveillance System Distributed Tracker (JDT) was designed by HughesAircraft Company for use in a laboratory environment in conjunction with Command and Control experiments in support of the air defense initiative. The tracker provides a live air picture for integration with the Air Defense Initiative Simulation for Command and Control (ADISC2). It was designed to accept radar inputs from up to ten (10) Joint Surveillance System (JSS) radars. The raw radar data is preprocessed and each radar report is tagged with a radar site ID. The data is then broadcast over an Ethernet to the JDT which resides on a SUN 4-260 workstation. A track file is then automatically established for each of the ten (10) radar sites using an N hit out of M scan approach. A master track store is then established through the correlation of the individual track files providing a single correlated air picture for the ten (10) radar sites. Automatic track initiation is performed over multiple radar scans. A one-plot track is formed initially. If on the next scan, a plot is correlated with a one-plot track, that track is upgraded to a tentative track.
