This e-book deals attention-grabbing insights into the foremost technical and clinical advancements within the historical past of radar, from the 1st patent, taken out via Hülsmeyer in 1904, via to the current day. Landmark occasions are highlighted and engaging insights supplied into the phenomenal those that made attainable the development within the box, together with the scientists and technologists who labored independently and below strict secrecy in numerous international locations internationally within the Thirties and the massive businessmen who performed an immense function after global conflict II. The publication encourages a number of degrees of analyzing. the writer is a number one radar researcher who's preferably positioned to supply a technical/scientific viewpoint in addition to a old one. He has taken care to constitution and write the e-book in the sort of means as to attract either non-specialists and specialists. The e-book isn't really subsidized through any corporation or physique, both officially or informally, and is hence totally impartial. The textual content is enriched by means of nearly 300 photographs, so much of that are unique and feature been accessed via exact searches within the information.

Martino (Padova) where the Naval Academy was transferred, and then to Brindisi, then back to Livorno. e. the use of radar. The application part is summarized in the table of contents of the manuscript, where the following aims are listed: 1. to detect the presence of a ship, invisible due to darkness or fog, 2. to measure its distance, 3. to determine its direction. Obviously the problem of naval combat was quite clear to Tiberio: in low visibility conditions it was impossible to correctly perform the classical procedures of (a) to detect an enemy ship, (b) to determine its direction and distance with optical means (naval rangefinder) (c) to calculate the aiming of the guns, (d) to adjust (tune) the shooting (gun laying), lengthening if the columns of water resulting from the projectiles were in front of the enemy ship, shortening in the opposite case.

A first type of them, operating in continuous wave, was made in ‘36–‘38 with some first, inadequate results; then different types operating in pulse mode were realized in ‘39 ÷ ’40. The first satisfactory results were obtained in ’40. ” Perhaps at this point the reader may be curious to know if the Gufo was actually used and on board of which ships. 3-bis or 46 2 The Owls and the Gufo. 30 Prof. Ugo Tiberio (left) and dr. 24 There are a very few images of Italian ships during the period 1941–1945 with radar on board, and in fact there were a few such ships and, see [Cer 95].

The use of ultra short wave was not attempted, yet, because the effects of reflection from these waves did not appear, at a first sight, such as to enable their practical use. In fact the waves from a reflective obstacle such as a ship or an airplane go back to the transmitter with an intensity which is very small in comparison to that of the direct field in the immediate vicinity of the oscillator, so it is very difficult to detect them. However, a careful examination of the question, and some data that I am collecting in the recent years, lead me to think that we can overcome this 16 2 The Owls and the Gufo.
