FIELD: electronic engineering. ^ SUBSTANCE: method involves applying two-channel transmitter having unit for building masking signals, the third adder unit, the third multiplier, the fourth adder unit, pseudo-random sequence generator and low frequency filter. Receiver unit has the third multiplier, synchronization unit, pseudo-random sequence generator with decoder connected to it, the first and the second delay units, controlled clock pulse oscillator, key unit and the second adder unit. Pilot signal is formed as complex signal built from four sinusoid oscillations. Each pair of the oscillations is phase-manipulated with its pseudo-random sequence. ^ EFFECT: data transmission protection against reconnaissance. ^ 14 dwg |
