From 1936 to 1942 he worked for the Air Ministry, where he helped to develop radar.

The Air Ministry was formerly a department of the British Government with the responsibility of managing the affairs of the Royal Air Force. Radar is a system that uses electromagnetic waves to identify the range altitude direction or speed of both moving and fixed objects such as Aircraft, ships He then joined the Tizard Mission and spent 3 years in Washington, D.C. to work with the Combined Research Group at the Naval Research Laboratory. The Tizard Mission officially the British Technical and Scientific Mission was a British delegation that visited the United Washington DC ( formally the District of Columbia and commonly referred to as Washington, the District, or simply D The United States Naval Research Laboratory (NRL is the corporate research laboratory for the United States Navy and the United States Marine Corps and conducts a After the end of the war he returned to Britain and rejoined the scientific civil service. A consultancy that had been set up by Sir Robert Watson-Watt, the father of radar, offered more interesting prospects for the conversion of wartime developments into peacetime technologies. Sir Robert Alexander Watson-Watt, FRS FRAeS ( 13 April 1892 &ndash 5 December 1973) is considered by many to be the " Hanbury Brown allowed himself to be recruited and worked as a consulting engineer until Watson-Watt decided to move the firm to Canada. After pondering a number of career possibilities, he returned to academia in the autumn of 1949, when he joined Bernard Lovell's radio astronomy group at the University of Manchester. Sir Alfred Charles Bernard Lovell - better known as Sir Bernard Lovell OBE PhD FRS (born 31 August 1913) is an English
At the Jodrell Bank Observatory of Manchester University, Hanbury Brown developed some of the earliest devices to be used in radio astronomy. Radio astronomy is a subfield of Astronomy that studies celestial objects at radio frequencies. He worked closely with the mathematician Richard Q. Twiss on the development of, amongst other things, radio intensity interferometry and the first optical stellar intensity interferometer, using army surplus searchlights as infinity focused photon collectors. Richard Q Twiss (1920 &ndash 20 May, 2005) is famous for his work on the Hanbury-Brown and Twiss effect with Robert Hanbury Brown. An intensity interferometer is the name given to devices that use the Hanbury-Brown and Twiss effect. Using this instrument he became the first person to measure the angular diameter of the star Sirius. Sirius is the brightest star in the night sky with a visual Apparent magnitude of &minus1 In 1962 he relocated to New South Wales in Australia to oversee the construction of the Narrabri Stellar Intensity Interferometer. Year 1962 ( MCMLXII) was a Common year starting on Monday (the link is to a full 1962 calendar of the Gregorian calendar. The Narrabri Stellar Intensity Interferometer (NSII was the first astronomical instrument to measure the diameters of a large number of Stars at visible wavelengths Two years into the task he resigned from the chair that had been created for him at Manchester and took up an appointment at the University of Sydney. The University of Sydney (informally Sydney Uni or USyd) is the oldest university in Australia After the Narrabri interferometer was decommissioned in 1974, having completed its task (to measure the angular diameter of 32 main sequence stars), he stayed on in Sydney to design a next generation instrument. This was not to be another intensity interferometer, but a modernised Michelson interferometer. As Hanbury Brown himself was keen to emphasize, the development of this technologically exceedingly demanding instrument -- the Sydney University Stellar Interferometer (SUSI) -- became essentially the project of his colleague John Davis. The SUSI opened in 1991.
In 1968, Hanbury Brown received the Eddington Medal jointly with Twiss. The Eddington Medal, named after Sir Arthur Eddington, is awarded by the Royal Astronomical Society nominally once every two years for investigations of outstanding For his efforts in developing the optical stellar intensity interferometer and for his observations of Spica, he was awarded the Hughes Medal in 1971. An intensity interferometer is the name given to devices that use the Hanbury-Brown and Twiss effect. Spica (ˈspaɪkə (also known as α Vir / α Virginis / Alpha Virginis is the brightest star in the Constellation Virgo, and the 15th brightest star The Hughes Medal, named after Microphone inventor David Edward Hughes, is one of several medals awarded by the Royal Society, England's reigning academy Year 1971 ( MCMLXXI) was a Common year starting on Friday (link will display full calendar of the 1971 Gregorian calendar. In 1982 he was named President of the International Astronomical Union, a title he retained until the end of his term in 1985.

He wrote an autobiographical account of the development of airborne and ground based radar, and his subsequent work on radio astronomy. Since he was rumoured to have been the original boffin who inspired the term, he called these recollections Boffin: A Personal Story of the Early Days of Radar, Radio Astronomy and Quantum Optics (ISBN 0-7503-0130-9). In the Slang of the United Kingdom, Australia, New Zealand and South Africa, boffins are scientists, Engineers
