Abstract: The paper presents the results of a study on rejecting anomalously large direction-finding errors from the results of instantaneous measurements of the ratio of the amplitudes of the output signals of the receiving antennas. Bearing rejection algorithms are based on theoretical dependences obtained for the normal model of fluctuations of the quadrature components of the output signals of the receiving antennas. The efficiency of algorithm rejection is determined by the terrain of open and semi-enclosed routes and may reach 54 percent.
