Radiogoniometry (direction radio) is widely used in aviation and in the Navy as a means of air and sea navigation, in military affairs, in determining the provisions of satellites, spacecraft, etc. The article describes a method for determining coordinates of the radio source and bearings when receiving a radio radiation source (SRE) using a nonlinear (including annular) antenna system (AS), an arbitrary shape consisting of poorly directed and directional elements (vibrators), and other methods of determining direction, for example based on the Doppler effect, radio imaging, and others. Multistage registration system, as featured on the ground, on aircraft is used. Improvement of the accuracy and reduction of the time to determine the origin of the radio source is achieved by using in determining the bearing of radio sources (SRE), a universal formula describing the complex envelope outputs of the AU, which allows us to obtain explicit expressions to calculate the amplitude and initial phase of the bearing signals. The collected values of bearings from different devices detect the signal of SRE using the methods of confluent analysis obtained equations of the lines in the plane and in space, the intersection of which determines the coordinates of the point estimates of the radiation source. For estimates of bearings and coordinates of the radiation source we obtained covariance matrix scattering estimates obtained from an ellipse or ellipsoid scattering unknown quantities.
