The book describes the methods of coordinate metering (determining the coordinates of the location of electronic equipment) in relation to radio monitoring using passive direction finding methods. The basis for the development of coordinate measurement methods is the energy principle. New methods of radio-electronic means co-ordination are considered, which are located both in one plane relative to the Earth's surface, and at different height (volume) arrangement of radiating and receiving antenna systems. A large statistical material is provided on the assessment of the systematic errors of the proposed methods. A method has been developed to improve the accuracy of determining coordinates.
