UNMANNED AERIAL VEHICLE CONTROL SIGNAL DETECTOR WITH ACOUSTIC DIRECTION FINDING CHANNEL Russian patent published in 2025 - IPC G01S13/86 G01S7/02 H04K3/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in radio monitoring means, radio direction finders, unmanned aerial vehicle (UAV) control signal detectors, 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 with determination of direction to RFS, including using acoustic sensors. Result is achieved due to implementation of acoustic channel of direction finding by maximum method based on directional microphone on support-rotary device with channel bandwidth corresponding to UAV engines sound frequency band. In the UAV control signal detector with an acoustic direction-finding channel, the direction to the mobile radio-frequency source is additionally determined by determining the direction of the acoustic signal source in the audio frequency band of UAV engines using the maximum method using a directional microphone.

EFFECT: broader functional capabilities of the device.
