The papers gathered by the members of the Naval Radar Trust mostly consist of reminiscences by over 150 staff who worked on British Naval Radar during WWII. These reminiscences survive in letters and transcripts of interviews, as well as some original technical papers retained by interviewees. The Trust also gathered material from other sources such as the Public Record Office and publications, therefore copies survive here of relevant material held elsewhere. The collection also includes the papers of the pioneering radio engineer Eric Megaw, a key figure in the development of the magnetron and cavity magnetron.
