Technique of Time-Frequency Analysis of a Series of Measurements of the Radiation Spectra of Night Mesospheric Ozone in the Millimetric Wavelength Range

Аннотация

A technique of time-frequency analysis of unevenly sampled data sets is developed to study variations in the night mesospheric ozone emission spectra obtained from ground-based millimeter-wave observations. Basic computational formulas as well as results of numerical simulations with monochromatic and noise signals are presented. The results of the simulation are in good agreement with theoretical estimates.
