FIELD: information technology.
SUBSTANCE: method of identifying a violator with determination of the direction of crossing a boundary is based on using two parallel wire transmission lines with in-phase coherent probing signals along the protected boundary to form two sensitive areas and with mutually-antiphase signs of the level of modulation of signals, which unambiguously correspond to the direction of movement of the violator when crossing the lines.
EFFECT: longer protected boundary and higher probability of correct determination of the direction from which it is crossed.
