The features of bearing information processing in a two-position radar system are considered. It is shown that in these systems, due to the absence of redundant information, the identification of bearings is a multi-alternative problem of statistical selection of hypotheses, the solution of which is especially important when locating a significant number of sources of active interference. The analysis of the matrix of coordinates of intersections of azimuthal bearings is carried out, a rule for identifying possible hypotheses of identification is formulated. To reduce the a priori uncertainty in the identification of bearings, it is proposed to use the energy differences of interference signals.
