The RIEC had been established in 1916 on the campus of the Italian Naval Academy in Livorno. Lieutenant Ugo Tiberio, a physics and radio-technology teacher on the Academy, was assigned to go the project on a part-time basis.
Shot noise is produced by electrons in transit throughout a discontinuity, which occurs in all detectors. There may also be flicker noise brought on by electron transit by way of amplification devices, which is decreased utilizing heterodyne amplification. Another reason for heterodyne processing is that for mounted fractional bandwidth, the instantaneous bandwidth increases linearly in frequency.
The one notable exception to heterodyne radar techniques is ultra-wideband radar. Here a single cycle, or transient wave, is used much like UWB communications, see List of UWB channels.
In 1937, while tests were being performed on this method, a passing flock of birds disturbed the sign. Realizing that this could be a possible method for detecting aircraft, the Minister of War ordered continuation of the experiments. Weiler and Gratama set about growing a system for directing searchlights and aiming anti-aircraft weapons.
In late 1942, IZZO was directed by the Minister of Defense to develop a radio-location (rádiólokáció, radar) system. Using journal papers on ionospheric …
