DEVICE FOR MEASURING PARAMETERS OF RADIO SIGNALS OF SPATIALLY DISTRIBUTED SYSTEM OF RADIO TRANSMITTERS USING UNMANNED AERIAL VEHICLE Russian patent published in 2024 - IPC G01R29/08 

FIELD: measuring.

SUBSTANCE: invention relates to devices for measuring characteristics of the electromagnetic field generated by a set of electromagnetic radiation sources using unmanned aerial vehicles (UAV) and can be used to measure parameters of radio signals of spatially distributed systems (SDS) of radio transmitters (RTS), simultaneously emitting at a single operating frequency incoherent special signals with the same spectrum width, but having distinctive personified structural-time features. Device consists of an on-board antenna, a tunable band-pass filter, a broadband power meter, an on-board GNSS signal receiver, on-board information storage, gyroscopic sensor, compass sensor, unit of matched filters, control unit and removable protected machine data carrier. On-board data storage device additionally contains M inputs, m=1, 2,…, M. Tunable band-pass filter has an additional input. Unit of matched filters consists of a heterodyne, a frequency converter, an analogue-to-digital converter, a quadrature frequency converter, M digital matched filters and M signal amplitude estimation devices.

EFFECT: providing the possibility of measuring at a given point in space both the total power of the set of all incoherent signals of the SDS of the RTS, and the amplitude of each of the incoherent partial signals of the RTS, which are part of the SDS of the RTS.
