Abstract. Electronic intelligence is an important element of electronic warfare, which «is not announced and never stops». The purpose of electronic reconnaissance is to detect the emitting radio-electronic means of a potential enemy, to determine its location and radiation parameters using passive (non-emitting equipment). Electronic warfare, even in peacetime, is a promising area of development. The use of passive methods allows work to be carried out covertly, without detection. The peculiarity of the proposed method is that a priori information about the objects that reflected the signal is not required. Determination of the coordinates of the emitter is carried out by determining the delay between the arrival of the direct signal and the set of reflections from the terrain. The use of detailed, for today, satellite maps of the terrain allow with some accuracy to determine the coordinates of reflecting objects on the ground. The coordinates of the receiving point can also be determined with high accuracy using global navigation systems. The data entered the computer and the recording of signals obtained as a result of observing the air allows us to determine the coordinates of the radio emission source. The algorithm proposed in the article allows reducing the number of receiving points to one and using a phase direction finder to determine the direction of signal arrival. Evaluation of the potential accuracy of the method showed the possibility of practical application, while better results can be obtained when improving the algorithm in terms of improving the algorithms for determining the times of arrival of signals, algorithms for their extraction and post-processing of experimental data.

Key words: radiolocation, Radar station, single-position method, radar, radio emission source, bearing.
