This new equipment, known as radar (…âradio detection and rangingâ), would play a major role during theÂSecond World WarÂand in subsequent conflicts.By the outbreak of the Second World War in 1939, a chain of early warning radar stations, called Chain Home (CH) stations, had already been built along the south and east coasts of Britain. Radar could pick up incoming enemy aircraft at a range of 80 miles and played a crucial role in theÂBattle of BritainÂby giving air defences early warning of German attacks.The CH stations were huge, static installations with steel transmitter masts over 100 metres high. But the invention of theÂcavity magnetronÂin 1940, which produced much more powerful radio waves with a shorter wave length, allowed far more compact, powerful and sensitive radar units to be produced. This gave the Allies an important technological advantage over designs used by the Axis forces, and new equipment was developed rapidly for use in aircraft and ships and in land warfare.
