The Battle of the Beams: The secret science of radar that turned the tide of the Second World War

Product Information

For the fabrication procedure, prepare enough reinforcement selections for all groups. First prepare the long spaghetti noodles by breaking them into 2- to 3-inch long lengths. Then measure out 3-4 g (~5 ml) of the shorter spaghetti noodles, rice and Nerds® candies and place them into individual plastic containers.

Prior to the war, Lufthansa and the German aircraft industry invested heavily in the development of commercial aviation and various systems and methodologies that would improve its safety and reliability. Among these was a considerable amount of research and development of blind landing aids which allowed aircraft to approach an airport at night or in bad weather. The primary system developed for this role was the Lorenz system, which was in the process of being widely deployed on large civilian and military aircraft.

Nerds® are made of sugar that may dissolve.**Whipple's story is based around Reginald Jones, a young British engineer who had a theory of how Germany's Luftwaffe was able to successfully find bombing targets at night: its aircraft were following ground-based radio beam transmissions. He convinced Winston Churchill of the importance of this aspect of aerial combat, and Britain was soon able to develop its own cavity magnetron (radar capable of amplifying electromagnetic waves) and other countermeasures. Relying on first-hand accounts from Reginald Jones as well as papers recently released by the Admiralty, The Battle of the Beams fills a huge missing piece in the canon of WW2 literature. It is a tale that combines history, science, derring do and dogged determination and will appeal as much to fans of WW2 history as to those fascinated by the science behind the beams that changed our lives.

To support this mission, the RAF invested heavily in navigation training, equipping their aircraft with various devices, including an astrodome for taking a star fix and giving the navigator room to do his calculations in an illuminated workspace. This system was put to use as soon as the war began and was initially regarded as successful. In reality, the early bombing effort was a complete failure, with the majority of bombs landing miles from their intended targets.

Experiments have shown that well-made beams shatter under high loading conditions. But after the British thwarted these assaults by putting out spoiler signals from UK transmitters on the same frequencies, the Germans devised the X-Gerat system. This was similar, but used several cross-signals to give greater accuracy. The destruction of Coventry on 14 November 1940 is testimony to just how devastating it could be. This involved acts of extraordinary heroism from pilots, agents and resistance fighters to gather information that Jones then used to help develop the systems that would eventually turn the tide in the Allies' favour.

The masterly crafted plot of this 'documentary thriller' is such that retelling it here would be a certain spoiler. Yet, I cannot refrain from revealing a totally unexpected (for me at least) final twist from the book's short postscript, in which the author introduces us to another real-life character – Admiralty scientist Raymond Whipple. Yes, the author's namesake. More than that: his own grandfather, who met his wife, Mary, the author's beloved 'Granny Mary', while researching radio waves. Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal its function and/or solve a problem. This sort of electronic warfare ( EW, in the lingo) is not new. It probably began in 1904 during the Russo-Japanese war. Although the shells of that era were dumb—the radar proximity fuze was 40 years away and GPS satellites more than 70—the age of radio had arrived. An enterprising Russian radio operator in Port Arthur drowned out transmissions from a Japanese warship that was helping correct naval gunfire. During the second world war, the so-called battle of the beams saw Britain jam and deceive radio signals used by German bombers to navigate to their targets. And as air power grew in importance through the cold war, finding and jamming the emissions of air-defence radars became vital.

Decoding the science in a digestible way for readers, The Battle of the Beams is a fantastic way into to a less discussed period of World War Two history. Britain at War Slip the pre-fabricated weigh pan/spring scale tension line apparatus over the mid span of the test beam. The Luftwaffe did not take such a fatalistic view of air warfare, and continued to research accurate night bombing against smaller targets. Not depending on celestial navigation, they invested their efforts in radio navigation systems. The Luftwaffe concentrated on developing a bombing direction system based on the Lorenz concept through the 1930s, as it made night navigation relatively easy by simply listening for signals on a radio set, and the necessary radios were already being installed on many aircraft.

Drones that have GPS jammed can resort to terrain matching: comparing images of the ground below to a stored map. The technique dates to the 1950s and is used by many cruise missiles, like America’s Tomahawk. But modern algorithms and computing power allow it to be done with remarkable precision, at lower cost and on a tiny chip.
