<name>IAP-P Doppler sounder spectrograms</name>
<description>
The continuous Doppler sounding is based on the measurement of Doppler shift, which
experience the radio waves that reflect from the ionosphere. The Doppler shift results
from the motion of reflecting level or from the changes of electron densities.
