Using a short-range microwave radio line allows to ensure high noise-resistance during transmitting discrete information to the vehicle with relative ease of technical implementation, including the case when the vehicle is in motion. Energy calculation of the shortrange radio line is carried out. Calculation of the noise-resistance of a short range duplex channel resistant to signal fading for coherent detection is carried out. A family of dependences of the signal power at the receiver input on relative positions of the receiving and transmitting antennas is obtained. The dependences of the error probability from the transmitted signal element on the signal-tonoise ratio are found for two practically significant cases: with and without the dominant brilliant point. It is shown that with fading of the microwave signal the error probability in the duplex channel can reach values smaller than 10−6…10−8 per sign.
