Polygon Representation of Target Location Uncertainty for Ocean Surveillance Application.

Abstract

This report describes polygonal location uncertainty representation and algorithms developed to use this uncertainty representation. The polygonal representation and algorithms provide a method for encoding and integrating target location information from many sources. The method has been implemented in an interactive FORTRAN IV computer program, which is described. Program output is graphically displayed. There are algorithms to fuse positive or negative location information with a target distribution, calculate the conditional probability that a location report originated from a particular target, move target uncertainty areas in time, and allow target uncertainty areas to move along or around land masses.
