Abstract
The present sounding apparatus is used for the detection and measurement of phenomena relating to the area surrounding the earth's globe. It can in particular be used in the study of the ionosphere and specifically for the study of limited amplitude, short duration modifications in the gradient of the electron density of the ionosphere. It can also be used for studying other phenomena, such as the study or monitoring of the sea swell.
