Radar was in its infancy at the start of World War II. The British were using radar effectively along their coastline with a network of ante nnas on 300-foot-tall towers to warn of approaching enemy aircraft and mis siles but they needed an invention that would allow radars to be small eno ugh to fit on ships and aircraft. They invented the cavity magnetron and l ooked to American manufacturing know-how and resources for rapid mass prod uction. They were turned down by all the major US firms\, but a small Bost on newcomer\, Raytheon Company\, responded with a solution. The once small company ended up making 85% of all magnetrons used by the allies in the w ar\; this changed the course of the war. By the end of World War II\, Rayt heon’s shipborne radars were on 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 visibility. Radar can be used to identify targets t o prevent fratricide\, deploy forces optimally\, for navigation\, for coll ision avoidance.\n\nEli Brookner\, global radar authority\, worked at Rayt heon Company from 1962 to 2014. Dr. Brookner will show just how dramatical ly the use of radar on aircraft and ships helped to destroy enemy aircraft \, ships\, missiles and submarines. How the use of miniature radars on the tops of artillery shells immensely increased their effectiveness against aircraft\, missiles\, infantry men and their equipment. These miniature TO P SECRET radars\, called proximity fuzes\, used miniature glass tubes whic h had to withstand 20\,000 g when blasted from the artillery guns. Raytheo n was one of the suppliers of these tubes. 22\,000\,000 proximity fuzes wi th 140\,000\,000 tubes were produced during WW II.\n\nCo-sponsored by: San Diego Chapter of the Aerospace Electronic Systems Society with the IEEE B oston Chapter\n\nSpeaker(s): Dr. Eli Brookner\, Distinguished Lecturer\, \ n\nAgenda: \n3:55 PM PACIFIC (6:55 Eastern) Joint Meeting - Registration i s collected through Boston\, watch out for time zone\n\n4:00 Speaker\n\n(V irtual Meeting)\, Connection information will be supplied to all preregist ered.\, San Diego\, California\, United States\, 92130 LOCATION:(Virtual Meeting)\, Connection information will be supplied to all preregistered.\, San Diego\, California\, United States\, 92130 ORGANIZER:kramer@sandiego.edu SEQUENCE:5 SUMMARY:How Radar Helped Win World War II -Distinguished Lecturer Eli Brook ner URL;VALUE=URI:https://events.vtools.ieee.org/m/238225 X-ALT-DESC:Description: <br /><p>Talk for the general public of all ages an d technical levels.</p>\n<p>Dr. Brookner will provide an easy to understan d explanation of how radar works.
