John Robert Mills was a Britishphysicist and scientific expert who played an important role in the development of Radar and the defence of Britain in After the war he continued his career working for various British government research establishments on a variety of projects until his retirement in 1977. In addition to many achievements and contributions to military technological development, Mills was the first British scientist to receive radio-wave signals bounced off the moon
Education and early career
Following his education at the Kingston upon Thames Grammar School he gained a BSc in physics at Kings College London in 1939 and later the same year he joined the Air Ministry Research Establishment in Dundee. In 1940 he moved to the Royal Aircraft Establishment at Farnborough and in 1942 moved to the Telecommunications Research Establishment in Malvern which later became the Radar Research Establishment and later still the Royal Radar Establishment where he stayed until 1960. John Mills was part of a ground breaking group during the Second World War that established Radar as both a meaningful defence, particularly against enemy aircraft, and guidance technology. This included air navigation systems and later, as a member of the Airborne Radar Division at RRE, the development of infra-red and radar targeting and reconnaissance systems for the Royal Air Force and Royal Navy. The equipment developed for navigation, targeting and reconnaissance was further advanced for inclusion in the V bomber force and the BAC TSR-2, the most technically advanced aircraft of its era, as well as the development of the first successful sideways looking reconnaissance radar which was further developed by the USA and led, amongst other things, to today's satellite radar systems.
1960-1967, MOD & RAE
Mills spent about a year at the Ministry of Defence, London followed by five years as head of Radio Department at RAE Farnborough where his responsibilities included: During this period his team received the first message bounced off the Moon from the USA, work which eventually led to modern satellite communications. He also worked in the development of the first automatic aircraft landing system. Mills was appointed Scientific Adviser to the Minister of Technology in 1966.
Night vision devices, mainly for the British Army where image intensifier technology was utilised in equipment from rifle sights to systems for tanks and other vehicles.
Tactical and strategic radio and communication network systems some of which were in active service till the early 2000s e.g. Clansman from the late 1970s till 2004
Military satellite communication systems with emphasis on light weight ground terminals for mobile use. e.g. Ptarmigan
The final chapter in Mills's career in the R&D business was a return to Malvern in 1976 as Deputy Director of the Royal Signals and Radar Establishment formed by merging RRE, SRDE and SERL as part of the program to rationalise the defence establishments. His team continued to work on advanced military and satellite communications. Mills held this post until his retirement in 1977.
Publications
Mills contributed to an article on radar published in the Encyclopædia Britannica Mills published "Radio Techniques for Automatic Systems in the Air" in the Journal of Navigation in 1960 Mills joint published "The Long-range Navigation of Civil Aircraft" in the Journal of Navigation in 1964
Personal life
Mills married Pauline Phelps in April 1950. He was very much a family man with keen interests in music and gardening, He was survived by his wife and two sons.
