DEVICE FOR DETECTION AND DETERMINATION OF AZIMUTH POSITION OF UAV Russian patent published in 2025 - IPC G01S13/88 G01S5/02 G01S7/38 G08G5/00 

FIELD: measuring.

SUBSTANCE: invention relates to UAV countermeasures, in particular to systems for radio-frequency detection of unmanned aerial vehicles (UAV) and determination of azimuth position relative to device, is intended for timely warning on appearance of UAVs or their control units in order to prevent their unauthorized use in the installation zone of the device. In the disclosed device, consisting of receiving antennae and a microcontroller, there are 7 broadband antennae with a beam width of 60°, 6 of which are receiving and are located along the perimeter of the device at angle of 60° to each other and at angle of 45° to the plane of the base of the device. Receiving antennae enable to determine the azimuthal position of the UAV relative to the device. One antenna located in the upper part of the device, the radiation of which is directed vertically upwards, makes it possible to implement the “UAV counter mode” at the UAV critical approach. A built-in accumulator is used as a power source. Device has a USB type-C connector intended for connection of an additional external power supply and for connection of a smartphone, through which the device parameters are set and viewed. Warning system used is a sound annunciator, an indicator of the azimuth position of the UAV relative to the device and indicators of the level of the UAV radio control signal in 2.4 GHz and 5.8 GHz frequency bands.

EFFECT: creation of a completely self-contained device for detecting and estimating the azimuthal position of the UAV relatively compact size and low weight, capable of notifying of the critical approach of the UAV using the sound and indicator built-in warning system, with the possibility of connecting an additional self-contained power supply, the possibility of setting and viewing parameters using a smartphone.
