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.
Keywords:
bearing, antenna systems, source of radio emission, iterative process,
the inverse matrix.
