With the end of the war in sight, we were able to publish the first full article on the fundamental principles of radar. Appropriately enough, the author was Smith-Rose, who, towards the end of World War I, had given our first detailed exposition of the amplifying valve. Pulse modulation, an offshoot of radar, was described later, as was the proximity fuse, 'a radio station in a shell nose-cap', which made use of the Doppler effect. The fuse marked the start of the trend towards miniaturization of components, one of the features of the coming decade.
