The algorithm of object identification during the structure and system monitoring of situation at a priori vagueness of the identifiable parameters has been built with the use of the criterion of maximum of likelihood function and maximum likelihood estimates of angular coordinates. Analysis of influence of accuracy of direction finding of aims on efficiency of acceptance of correct and erroneous decisions about identification has been carried out on the basis of its statistical tests. The probabilities of correct and false identification of the objects taken the bearing by monitoring facilities with multi-beam aperture antennas have been investigated.
