SIGNAL-INTERFERENCE COMPLEX Russian patent published in 2019 - IPC G01S7/38 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering and can be used to generate a signal-noise environment in the interest of substantiating characteristics and parameters of radioelectronic equipment (REE) for evaluating their electromagnetic compatibility and noise immunity. Signal-jamming complex comprises a receiving antenna, in series connected to a receiving-excitatory unit, which are located in the ground part of the device, and also comprises an unmanned aerial vehicle (UAV), which is an onboard part of the device, on which there are: on-board control device of micro-computer, as well as onboard flight controller and onboard UAV control device, interconnected, wherein ground part of device comprises ground control computer, first output of which is second input of receiving excitation unit, connected by output to its first input, second output of the ground-based control computer is the input of the microcomputer located in the ground part of the control device, which is connected via a radio channel to the on-board micro-computer control device, the third output of the ground-based control computer is the input of the UAV control device located in the ground part, which is connected via a radio channel to the on-board control device UAV, and the output of the third input of the ground-based control computer, also includes a test REE, as well as a UAV-arranged transceiving antenna connected via a radio channel to a receiving antenna located in close proximity to the phase center of the tested REE, and the REE under test, which output is input of receiver in series connected to demodulator, which output is second input of digital-analog formation of signal-to-noise ratio (DAF SNR) sub-module, which first output is input of receiving-transmitting antenna, and second output is input of on-board control device of micro-computer connected by its output to first input of submodule DAF SNR.

EFFECT: high quality and efficiency of substantiating REE parameters for evaluating their electromagnetic compatibility and noise immunity.
