FIELD: radio engineering.
SUBSTANCE: device belongs to radio engineering. The effect is achieved by the fact that a device containing a block of modulators (1), the first (2.1) and second (2.2) mixers, a frequency generator (3), a block of pseudo-random (GPS) code generators (5), the first (4.1) and the second (4.2) frequency synthesizers, a wideband filter (6), the first bandpass filter (7.1) and a block of demodulators (8), a block of encoders are introduced, (9) a second bandpass filter (7.2), a transmitter (10), an antenna (11), low frequency amplifier (21), intermediate frequency amplifier (12) and high frequency amplifier (13), control device (14), synchronization device (15), decoder unit (16), first (17.1) and second (17.2) electronic keys , a computing device (18), a digital-to-analog converter (19), an automatic gain control detector (20), a low-pass filter (22), an analog-to-digital converter (24), a measurement unit (23).
EFFECT: decreased efficiency of unauthorized information retrieval.
