The new CAS-DIS digital ionosonde
Annals of Geophysics, 2013 A high quality digital ionosonde called the Chinese Academy of Sciences digital ionosonde (CAS-DIS) has been developed for investigations of the ionosphere. Two important features are used for the CAS-DIS; first, the technique of analog down-conversion has been replaced by the new approach of digital down-conversion technology.
