The expected high saturation of war zones radio emission sources (RES) of different function creates complicated (multi-target) electronic environment and predetermines for systems of radioelectronic intelligence (ELINT) basic necessity of the decision of following problems: - identifications RES on types, copies and tactical purposes; - tracking detected RES on all significant information parameters: to carrier frequency, pulse time, pulse duration, spectrum width, location, etc. The urgency of the decision of these problems is caused, in particular, by necessity of an threat-s estimation with ranging RES on relevance degree. Success of the decision of these problems in multi-target environment in many respects depends on ELINT-s ability to identify the received signals with concrete copies RES. It predetermines potential possibilities of their authentic tracking. Special complexity The problem of single-type RES identification not resolved on signal parameters is especially complicate. The purpose of the present work is development of simple and effective mathematical apparatus for signal-s identification. The method of an identification of the received signals with concrete detected (tracked) copies RES in the multi-target environment, based on use of multidimensional strobes (confidence intervals) on measured phase co-ordinates is offered. As a result of work performance: 1) the settlement mathematical formulas necessary for definition of the identification strobe sizes depending on set probability of hit of results of measurement of parameters of signals in limits of a strobe are offered; 2) the decision rule for signal identification is resulted. The offered method is universal, simple in technical realization and does not show high requirements to computing resources. The literature list contains 7 names.
