RADIO RECONNAISSANCE STATION Russian patent published in 2009 - IPC G01S7/285 

FIELD: physics; radio.

SUBSTANCE: invention relates to radio engineering and provides for radio reconnaissance of potential enemy electronic means. Radio reconnaissance station comprises antenna unit, receiver, direction finding unit, received signal parameters' analyser, data storage and processing device and telemeter. Antenna unit comprises receiving antennas; receiver comprises receiving antenna, readjustment unit, the first and the second oscillators, the first and the second mixers, first intermediate frequency amplifier, detecting device, first delay line, first, second, third, fourth and fifth keys, second intermediate frequency amplifier, frequency meter, spectrum width comparator, data storage unit, phase doubler, first and second spectrum width meters, spectrum width comparator, frequency discriminator, fourth and fifth narrow-band filters, phase scale-of-two circuit and second phase discriminator. Direction finding device comprises receiving antennas, mixers, first intermediate frequency amplifiers, three multiplying units, narrow-band filters, engine, reference generator, second delay line, first phase discriminator, first and second phase meters.

EFFECT: enhanced operational capabilities of the station due to measurement of carrier frequency of signals being surveyed, discrimination and selection of complex PSK and PWM signals, detection thereof and measurement of parameters.
