METHOD FOR AUTOMATIC DETECTION OF NARROW-BAND SIGNALS Russian patent published in 2023 - IPC H04B1/10 H04B1/71 

FIELD: radio engineering.

SUBSTANCE: invention is related to methods for detecting narrow-band signals in additive noise under conditions of a priori uncertainty about the time of their arrival. The method for automatically detecting narrow-band signals additionally consists of forming a new time fragment of the input implementation in such a way that the contour of the calculated new working cross-correlation function is completely displayed within the new fragment, and then the time is determined from the maximum value of the cross-correlation function and the corresponding time value detecting a useful signal.

EFFECT: selection of the boundaries of the processed time fragment of the input implementation in such a way that the contour of its cross-correlation function with a pre-generated reference signal is completely displayed on the oscilloscope screen.
