Abstract
The Spectral Airglow Temperature Imager is an instrument, specially designed for investigation of the wave processes in the Mesosphere-Lower Thermosphere. In order to determine the kinematics parameters of a wave, the values of a physical quantity in different space points and their changes in the time should be known. An approach for image processing of registered spectrograms is proposed. A detailed description is made of the steps of this approach, related to recovering CCD pixel values, influenced by cosmic particles, dark image correction and filter parameters determination.
