Abstract
Determination accuracy analysis of the radio emission sources. The techniques of radio emission sources, which are intended to identify and analyze radio obscure rays to identification sources of signals and interference, measurement signals and interference on the basis of extreme statement of the time- difference of arrival. The purpose of a theoretical study of radio techniques used in various fields of radio control. Task work is to study methods of radio, the effectiveness and accuracy of radio equipment. Coordinates are defined by the minimization of square functional that allows to consider information redundancy of the system and by that considerably to raise the coordinates determination accuracy. Statistical modeling scheme, and also the statistical characteristics analysis of the above-named system is provided. 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.
Keywords: radiomonitoring, radio emission sources, methods for accuracy enhancement.
