During the Battle of Britain in 1940, radar allowed the Royal Air Force to
position its fighters to attack incoming German aircraft. Radar developed
rapidly during the Second World War, and was widely used in land, air and sea
operations. Louis Brown’s A Radar History of World War II contains interesting
new material from Germany, Japan, Russia and the British dominions. A great one
for the reference shelf. Published by the Institute of Physics,
