Annotation: A method for accuracy enhancement of radiation source positioning by the range difference method with the use of passive satellite system, which is intended for radiomonitoring, is considered. An algorithm for cooperative signal processing in two-input antenna system is suggested. The results of mathematical modeling are presented.
