Elliptical Error Statistics for Radiolocation Analysis
Richard L. Johnson · IEEE Transactions on Aerospace and Electronic Systems · 1978
A review is made of current techniques used in the statistical analysis of radio direction finding data which predict a region of probable transmitter location based upon a collection of intersecting lines of bearing measurements. This region has been conventionally defined by the elliptical error probability (EEP). Two characterizations for EEP are considered, and a technique is proposed for robust estimation of the elliptical region of probable location.
