METHOD OF DETERMINING THE ANGULAR POSITION OF THE OFDM SIGNAL SOURCE Russian patent published in 2019 - IPC G01S5/00 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering and can be used, for example, for passive determination by mobile measuring point of angular position of signal sources using orthogonal frequency division multiplexing (OFDM). For this purpose, in the method, measuring and memorizing the directions of the mobile reception center velocity vector and module, using the received OFDM signal values as the criterion of the sub-carrier frequencies estimation accuracy, successful extraction of information messages, determination of the angular position of the source of the OFDM signal based on differences in estimates of frequencies of subcarrier frequencies of the received OFDM signal and module of the speed vector of the mobile receiving point.

EFFECT: technical result is determination of angular position of OFDM signals sources, which expands functionality of method of OFDM signals reception, does not require knowledge of real radiation frequency of radio-frequency source and application of complex multichannel devices.
