METHOD FOR DETERMINING FREQUENCIES OF MULTIPLE SIGNALS IN SUBSAMPLING RECEIVER Russian patent published in 2021 - IPC G01R23/16 H04B1/74 

FIELD: radio engineering.

SUBSTANCE: method relates to the field of radio engineering and can be used for broadband analysis of the electronic situation. A multi-channel receiver is being used. Each channel performs analogue-to-digital conversion, amplitude spectrum computation, and signal detection. The signals detected in the channels are compared in frequency and amplitude. When the signals coincide, a decision is made about their existence at these frequencies. The decision on the coincidence of the signals in amplitude is taken if the ratio of the amplitudes of the output signals for each pair of channels is within the specified limits.

EFFECT: ensuring the possibility of determining the frequencies of time superimposed signals in the receiver with subsampling while reducing the number of processing channels.
