DEVICE FOR SIMULATING RADIO EMISSION SOURCES WITH ARBITRARY TYPES OF SIGNALS Russian patent published in 2024 - IPC G01S7/38 G01S7/40 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in means of radio monitoring, radio interference, signal simulation, as well as similar means and systems, in which radio signals of radio-frequency sources (RFS) are detected in conditions of noise of unknown intensity and generation of signals identical to those detected for the purpose of uncompromising blocking of their RFS or simulation of operation of RFS with arbitrary types of signals. Device for simulating radio emission sources with arbitrary types of signals further comprises first, second and third switches, third storage register, third and fourth quadrature phase detectors, first and second differentiators, second adder, digital-to-analogue converter, transmitting and receiving log-periodic antennae, first and second rotary supports, first and second control units, first cosine-sine generator, maximum selection circuit, power amplifier. Output of the transmitting log-periodic antenna is the output of the device. First input of the receiving log-periodic antenna is the input of the device.

EFFECT: possibility of recording in-phase and quadrature components of the received signal with its subsequent transfer to a radio frequency, conversion into an analogue form and radiation in the direction of radio-frequency sources, which will allow transmitting the same information to a correspondent, thereby uncompromising blocking the operation of this communication or control line, or simulating operation of the radio-frequency source with arbitrary types of signals.
