An ea sy to understand explanation of how radar works will be given. Radar was i n its infancy at the start of World War II. The British were using radar e ffectively along their coastline with a network of antennas on 300-foot-ta ll towers to warn of approaching enemy aircraft and missiles but they need ed an invention that would allow radars to be small enough to fit on ships and aircraft. They came up with the cavity magnetron invention. They look ed to American manufacturing know-how and resources to mass produce this d evice in a hurry. After turndowns by all the major US firms\, a small Bost on newcomer\, Raytheon Company\, came up with a solution and ended up maki ng 85% of all magnetrons used by the allies in the war\, and changed the c ourse of the war. By the end of WW II Raytheon’s shipborne radars were o n all allied ships military and civilian. Radar can see at night\, through clouds\, in and fog. Radar can be used to land aircraft in zero visibilit y. Radar can be used to identify targets to prevent fratricide\, deploy fo rces optimally\, for navigation\, for collision avoidance.\n\nEli Brookner \, who worked at Raytheon Company from 1962 to 2014\, will show just how d ramatically the use of radar on aircraft and ships helped to destroy enemy aircraft\, ships\, missiles and submarines. How the use of miniature rada rs on the tops of artillery shells immensely increased their effectiveness against aircraft\, missiles\, infantry men and their equipment. These min iature TOP SECRET radars\, called proximity fuzes\, used miniature glass t ubes which had to withstand 20\,000 g when blasted from the artillery guns . Raytheon was one of the suppliers of these tubes. 22\,000\,000 proximity fuzes with 140\,000\,000 tubes were produces during WW II. Radar was used with the atomic bombs. Eli holds a bachelor’s degree in Electrical Engi neering from The City College of New York and a Master’s and D.Sc. degre e from Columbia University. He is the author of four books on radar\, ante nnas and tracking\, has published more than 230 papers\, and has taught co urses on Radar\, Phased Arrays and Tracking in 26 countries to over 10\,00 0.\n\nWebEx information will be sent to your email prior to Wednesday\, Au gust 26th!

An easy to understand explanation of how radar works will be given. Radar was in its infancy at the start of World War II. The Briti sh were using radar effectively along their coastline with a network of an tennas on 300-foot-tall towers to warn of approaching enemy aircraft and m issiles but they needed an invention that would allow radars to be small e nough to fit on ships and aircraft. They came up with the cavity magnetron invention. They looked to American manufacturing know-how and resources t o mass produce this device in a hurry. After turndowns by all the major US firms\, a small Boston newcomer\, Raytheon Company\, came up with a solut ion and ended up making 85% of all magnetrons used by the allies in the wa r\, and changed the course of the war.
