Ionosphere sounding
WebIonospheric soundings are performed by so called ionosondes. Ionosondes are radar systems that sweep their transmitted frequency from 1 MHz to about 20 MHz. This is the … Webincreasingly used since they can measure the ionosphere over regions where ground-based sensors cannot easily be located, such as the oceans. This paper is concerned …
