METHOD OF DETERMINING FREQUENCY AND DEVICE FOR IMPLEMENTING METHOD Russian patent published in 2008 - IPC G01R23/00 

FIELD: physics; measurements.

SUBSTANCE: method and device can be used for determining carrier frequency and other parameters of signals with amplitude modulation, in a given frequency range, and formation at that frequency, of target noise interference for jamming a radioelectronic device. The device consists of primary and secondary antennae, primary and secondary input circuits, scanning unit, primary and secondary high frequency amplifiers, heterodyne, primary and secondary mixers, primary and secondary amplifiers of intermediate frequency, primary and secondary detectors, video amplifier, device for generating time-base, cathode-ray tube, video pulse generator, three switches, a generator of intermediate frequency, multiplier, summation frequency filter, amplitude modulator, noise generator, power amplifier, transmission antenna, divider, threshold unit, amplitude limiter, synchronous detector, recording unit, and primary and secondary units for controlling direction diagram. The technical outcome is the increased functional capabilities of the method and device through determination of other parameters of the received AM-signal and direction on the target radioelectronic device and formation of retransmitted noise interference targeted at the radioelectronic device.

EFFECT: more functional capabilities of the method and device of determining carrier frequency.
