MULTIFUNCTIONAL COMPLEX OF MEANS OF DETECTION, TRACKING AND RADIO COUNTERMEASURES TO THE APPLICATION OF SMALL-CLASS UNMANNED AERIAL VEHICLES Russian patent published in 2022 - IPC F41H11/04 G01S13/00 G01S7/38 B64C39/02 

FIELD: radio location.

SUBSTANCE: invention relates to the field of countermeasures to performance of tasks of a UAV and can be used for comprehensive monitoring of the air situation, detection, direction finding, recognition and neutralisation of operation of the UAV equipment. The complex is based on active and passive radio location systems, an electro-optical system, a radio suppression system, an information processing and storage apparatus, and a navigation and orientation module. The solid-state digital active phased array antenna array and the pulse-Doppler multipath three-dimensional radar of the S frequency range included in the active radio location system, together with the control and processing server, provide a possibility of simultaneous operation in the emission and reception modes in several spatial directions with varying signal characteristics. The passive radio location system is based on a distributed system with N, wherein N is no less than two, remote posts, wherein each post includes a two-dimensional detector direction finder and navigation and time-referencing equipment.

EFFECT: accuracy of detection and possibility of countering the UAV is increased.
