Ionosonda SDR per sondaggi obliqui

Abstract

The aim of the project is to carry out a prototype of an ionosonde for oblique sounding, based on the frequency modulated continuous wave principle and implemented by means of innovative programmable devices that allow creating smaller and more transportable instruments with respect to the classic ionosondes. The SDR ionosonde is a bistatic radar composed by a transmitter, which can simultaneously serve several receivers placed in different locations, and by one or more receivers that can tune in to different transmitters, sounding at different times. The surveys allow to map the ionosphere in various parts of the territory for the verification of the theoretical models of the ionosphere and to study the local variations of the Total Electronic content (TEC) as earthquake precursors.
