Abstract. The possibility of assessing the distance from the aircraft to an operating ground-based radar based on the totality of reflections of its signals from the terrain and local objects is evaluated. The peculiarity of the measurement algorithm is that a priori it is not necessary to know from which object one or the other signal was reflected. The coordinates of the reflectors are stored in the computer memory in the form of an electronic map of the area. The position of the radio emission source is determined by the difference in the arrival times of the direct and reflected signals, as well as the bearings measured from them.
Key words: single-position method, passive systems, aircraft, range determination, direction finding.
