In article the analysis of different ways of two-stage identification of bearings of sources of radio emissions (SRE) in the integrated mnogodatchikovy multiposition systems of radio monitoring of air basing is given and real feasibilities of these ways and restrictions inherent in them are defined. Features of functioning of algorithms of strobe and besstrobovy identification of results of the mea-surements used on the first identification stage are analyzed. The space and sheet ways of interposition identification applied on the second stage of identification of bearings in situations when SRE are indiscernible in radio engineering parameters of their signals are considered. 

The general information about ways and algorithms of identification of bearings based on use of space invariants, spatio-temporal in-variants, invariancy of height of SRE, complanarity of vectors of pelengatsionny triangle, choice of the smallest perpendicular between lines of bearing concerning bearing of basic position which provide the solution of problems of monitoring of SRE in three-dimensional space at certain restrictions is given. Also the characteristic is given to known ways of sheet identification in the course of which selection of true and false points of intersection of bearings on the plane with use of kinematic parameters of the movement SRE is carried out.
The conclusion that the existing ways of interposition identification have essential shortcomings that seriously limits areas of their practical application is drawn and causes need for development of new ways of identification. One of such ways is the way of identifi-cation of bearings with use of external targeting about space coordinates of SRE allowing to simplify considerably procedure of inter-position identification of bearings.
