A Graphics Program for Updating the Confidence Region of a Target.

Abstract

A graphics program for updating the confidence region of a surveillance target subject to specified velocity constraints has been developed. The program is designed to operate in an interactive mode at a graphics terminal interface of an ocean surveillance information processing system. The initial confidence region of the target is assumed to be provided by a sensor contact report. The constraint set of velocities is specified in terms of upper and lower bounds on speed and heading and is either provided by a contact report or is selected by the ocean surveillance analyst. The program displays the original and updated confidence regions. This program can be implemented on a graphics interactive system driven by a minicomputer. (Author)
