FIELD: radio engineering.
SUBSTANCE: method relates to radio engineering. The effect is achieved by the fact that in the transmitting station programmatically, in accordance with the values of the random numbers that are generated by the generators of pseudo-random (PRG) codes, the type of modulation, the coding method, the signal power, the moment of signal emission, its polarization, the signal frequency are changed in the pseudo-random frequency hopping (PRFH) mode or using an algorithm other than the PRFH algorithm. This changes all parameters or some of them and their values. In the receiving station, the set of used parameters and their values are changed synchronously with the transmitting station, ensuring the reception of a signal with the appropriate modulation, coding method, the moment of signal arrival, signal power, its polarization, and frequency. The stations use PRG codes with identical characteristics. When using a change in the signal power, preliminary, using test sequences, the values of the receiver parameters are determined, which provide the best conditions for receiving information for possible values of the gradations of the change in the signal power.
EFFECT: increasing the security of transmitted information from unauthorized reception.
