Analisi e progettazione di elementi radianti d'array in banda HF per radar OTH
Questo lavoro di tesi è incentrato sullo studio di antenne operanti in banda HF e quindi nell’intervallo di frequenze che va dai 2 ai 30 MHz. In particolare, l’attenzione è stata focalizzata sul dimensionamento e la configurazione di possibili elementi ...

Studio di tecniche innovative nei radar Over the Horizon (OTH)
Esaminando le peculiarità e le criticità dei sistemi radar OTH (Over The Horizon) che operano per riflessione ionosferica, si evince ben presto che queste si discostano profondamente dalle relative caratteristiche riscontrabili nei radar a microonde.
