Radar

Since a fairly large percentage of the effort of physicists and electrical engineers in this country and in England was expended on radar development during the war, techniques in electronics have advanced at possibly ten times the normal peacetime rate. The purpose of this paper is to give a brief survey of the wartime developments in electronics and to show how these were used in a few radar sets. Because the applications of radar to civilian activities will probably be of minor importance when compared with the sum total of other electronic applications, this survey makes no attempt to give a complete description of any particular radar set. Those readers who are interested in a detailed description of a radar installation will find complete inforrration on the SCR-268 in the literature.
