Abstract
The relation connecting the probability of detecting the operating of wireless digital communication systems (DCS) depending on the size of the aperture of diverting and legitimate channels and their relative position was derived. It was shown that the main factors affecting the efficiency of detection are removal of the legitimate and side channel receiving aperture from the aperture of the emitters and scatterers of the information source, as well as the value of the secret speed. Specific quantitative data on the size of apertures and diverting legitimate channels, as well as their mutual arrangement in which DCS signals can be confidently identified, were obtained.
KEY WORDS: legitimate channel, wiretap channel, aperture, probability of detection, system of radiators and scatterers, secret speed
