Abstract

Algorithms of filtration for atmospherics and narrow-band noises in VLF spectrograms have been developed. An algorithm for whistler detection in a spectrogram has been suggested. It is based on a nonlinear transformation of «time-frequency» coordinates to rectify a whistler pattern followed by the recognition of this straight line.
