The article describes a
method for isolating the signal chirp Ionosonde in the frequency domain. The
method takes into account that the mode of ionospheric propagation contains
readings that are not abnormal for the given sample. The method is based on a
two-stage sampling censoring based on the criterion of abnormal discharge
readings and threshold criteria, taking into account the empirical evaluation
of the broadening of the mode.
