SPATIALLY DISTRIBUTED RADIO INTERFERENCE SYSTEM ON UNMANNED AERIAL VEHICLES Russian patent published in 2023 - IPC G01S7/38 G01S19/21 H04K3/00 

FIELD: electronic warfare.

SUBSTANCE: invention can be used for radio jamming of radio communications. The declared system on unmanned aerial vehicles (UAVs) provides operation not only in the “Response Interference” mode, during which synchronous radio interference is generated from all N aperture UAVs 2_n, n=1, ..., N, in response to radiation of irradiated radiation at the signal frequency IRI, which ensures an increase in the level of radio interference in times, but also in the “Targeted Interference” mode, during which spatially targeted synchronous and in-phase radio interference is generated at a given frequency from all N aperture UAVs 2 _n, n=1, ..., N, which ensures an increase in the level of radio interference at the object’s location radio jamming in times. The system consists of N aperture UAVs with a radio jamming station and an irradiator UAV with a control station located. The claimed system, located on each of the N UAVs, additionally includes a matched filter, a phase shifter and a switch, and transmitting and receiving antenna arrays are used as the transmitting antenna and receiving antenna. The control station located on the UAV-irradiator additionally includes a pseudo-random sequence generator and a target designation device.

EFFECT: ensuring the operation of the radio interference system in the mode of setting up spatially targeted coherent radio interference according to target designation from a ground control point.
