Testing and Combination of Confidence Ellipses: A Geometric Analysis.
Abstract
This document is one of a series of algorithm analysis reports performed for the US Army Intelligence Center and School covering selected algorithms in existing or planned Intelligence and Electronic Warfare (IEW) systems. This report proves several properties of the ellipse combination process as used in correlation algorithms, both alone and in combination with the associated statistical tests. In particular, it is shown that the statistical tests introduce order dependence to the combination process. A confidence ellipse, sometimes called an EEP, is one of the ways in which intelligence data concerning an emitter's location is summarized. Such an ellipse is always centered at the estimated emitter location and is a measure of the possible error in the location estimate. The goal of this paper is to examine the geometric implications and properties of the statistical test for deciding whether two estimates refer to the same emitter, and of the method of combination for confidence ellipses.
