ELECTRONIC RECONNAISSANCE STATION Russian patent published in 2007 - IPC H04K1/10 G01S13/34 

FIELD: radio engineering, possible conduction of electronic reconnaissance of radio-electronic devices of possible opponent (radiolocation stations, communication and management radio lines, etc).

SUBSTANCE: electronic reconnaissance station contains antenna device, receiver, direction-finding device, analyzer of parameters of received signal, device for memorizing and processing received information, telemetric device and control station receiver, where receiver contains receiving antenna, adjustment block, first and second heterodynes, first and second mixers, amplifier of first intermediate frequency, detector, delay line, key and amplifier of second intermediate frequency, direction-finding device contains receiving antennas, mixers, amplifiers of first intermediate frequency, motor, supporting generator, multipliers, narrowband filters, phase detector, two phase meters, telemetric device contains set-point generator, generator of analog messages, analog scrambler, amplitude modulator, generator of discontinuous messages, digital scrambler, phase manipulator, power amplifier and transmitting antenna, control station receiver contains receiving antenna, high frequency amplifier, heterodyne, mixer, intermediate frequency amplifier, amplitude limiter, synchronous detector, analog descrambler, registration and analysis block, demodulator of phase-manipulated signals, multipliers, narrowband filter, low frequency filter and digital descrambler.

EFFECT: increased trustworthiness of transmission of analog and digital information from onboard a helicopter to control station by protecting it from unsanctioned access and using complex signals with combined amplitude modulation and phase manipulation.
