Statistical theory of passive location systems
Abstract
A derivation of the principal algorithms and an analysis of the performance of the two most important passive location systems for stationary transmitters, hyperbolic location systems and directionfinding location systems, are presented. The concentration ellipse, the circular error probability, and the geometric dilution of precision are defined and related to the locationsystem and receivedsignal characteristics. Doppler and other passive location systems are briefly discussed.
