One-Stage Estimation of the Position of a Radio Source by a Combined Passive System

摘要

An algorithm for one-stage estimation of the radiator position by a combined passive system consisting of narrow-base subsystems is synthesized and analyzed. The Cramer-Rao matrix bound of coordinate measurement errors is calculated for the one-stage algorithm. A comparative analysis of the system based on the synthesized algorithm and the previously studied one-stage wide- and narrow-base systems is performed. It is shown that, in a number of cases, the system based on the proposed algorithm can ensure a considerable advantage over the known systems in terms of measurement accuracy.
