Abstract
Determination of the location of radio-electronic means radiating into the air is one of the main tasks of radio control, and under conditions of a priori uncertainty about the parameters of radio emission sources, the highest accuracy of coordinate estimation has a time difference of arrival method. The paper proposes a new approach to determine the coordinates of radio emission sources using a single-position mobile meter based on the difference-distance direction finding. In contrast to the known ones, it allows reducing the number of measuring points of the difference-distance direction finding system without worsening the accuracy of estimating the coordinates of radio emission sources owing to using the moving meter and the method of maximum likelihood to calculate the coordinates in multiple measurements. The practical application of the developed approach is expedient in the development of radio control complexes and allows not to take into account the orientation of the meter on an unmanned aerial vehicle in space, as well as to increase the accuracy of radio emission source coordinates determination.
