Automatic tracking techniques for surveillance radars / by A.W. Bridgewater. : Co24-3/7-1357-1982E-PDF

"This report is a survey of target tracking techniques for automated radar surveillance. It does not go into great technical detail, but attempts to highlight the important issues and to indicate how they are related. These issues are: 1) the choice of coordinate system in which to make target measurements, to initiate or associate tracks, and to update and display these tracks; 2) the choice of filter for prediction and smoothing of track data; 3) the techniques to be employed for conflict resolution, when ambiguities arise in the association of new target observations with existing tracks; 4) the use of manoeuvre-detection procedures, when the target-in-track deviates from its modelled mode of behavior; and 5) the process of initiating a new track automatically, by combining past measurements to form a likely trajectory of a target of interest. An extensive bibliography pertaining to these topics is provided"--Abstract, page 1.
