In the same year, together with his colleague Professor Nello Carrara, Tiberio developed a system for the localization of objects at a distance with magnetic waves called the EC1 "radio telemeter", an early form of radar.

[1][2][3][4] Tiberio was recalled into service in January 1937, following Italy's involvement in the Spanish Civil War, resuming his studies within the Royal Electrotechnical and Communications Institute (Regio Istituto Elettrotecnico e delle Comunicazioni della Marina, RIEC) in Livorno, where he worked until 1943.

He also suggested the use of the Doppler effect for locating vehicles; he developed a device based on this principle which he called the radiotachometer, due to the greater accuracy in measuring the speed of objects.

Only after the defeat suffered in the nocturnal battle of Cape Matapan, in March 1941, the importance of his work was reevaluated, and he was summoned by the Italian Supreme Command and requested to build a functional radar as soon as possible.

[1][2][3][4] After the war, Tiberio continued his research work in the field of applied electronics, telecommunications, electromagnetic propagation and bioengineering, publishing numerous essays and writings.
