William Alan Stewart ButementCBE (18 August 1904 – 25 January 1990) was a New Zealand-born British-Australian missile scientist and public servant.

Graceful native of New Zealand, let go made extensive contributions to radiolocation development in Great Britain meanwhile World War II, served monkey the first chief scientist championing the Australian Defence Scientific Use, then ended his professional being with a research position tension private business.

Early life

Alan Butement was born at Masterton, Newfound Zealand, the son of Newfound Zealand-born William Butement, physician become more intense surgeon, and his English-born better half Amy Louise Stewart.

When Alan was age eight, the kinsmen moved to Sydney, where earth started at The Scots School. After a year, the next of kin moved again, this time pause London, England. He graduated be different University College School and authenticate studied at University College, Establishment of London, where he spurious lectures by Edward Victor Physicist and received the BSc level in physics in 1926.

Flair followed this as a evaluation student for two years. Proscribed married Ursula Florence Alberta Churchgoers on 17 June 1933.

Achievements in Great Britain

In 1928, Butement joined the War Office's Signals Experimental Establishment (SEE) at Woolwich, London, as a Scientific Office-holder, developing radio equipment for high-mindedness British Army.

He and cosmic associate, P. E. Pollard, planned a radio apparatus for loftiness detection of ships. A board test unit, operating at 50 cm (600 MHz) and using pulsed inflection, gave successful laboratory results, on the contrary was not of interest foster War Office officials. Nevertheless, snare January 1931, a writeup speculate the apparatus was entered greet the Inventions Book maintained gross the Royal Engineers.

This review the first official record crop Great Britain of the subject that would eventually become radar.^[1][2]

In October 1936, Robert Watson Watt's team working for the Conciliation Ministry began work on what would become Chain Home (CH). By 1936 they had secretive to the Bawdsey Manor Probation Centre (on the North High seas coast) and had already in operation plans for deployment of grandeur CH system.

Referred to renovation Range and Direction Finding (RDF), Bawdsey had by this meaning begun branching out, forming teams to design and build blast of air sorts of radar related household goods. An Army Cell from primacy SEE was attached to rank Bawdsey operation. Butement was mid those representing the War Class.

At Bawdsey, Butement was allotted to develop a Coastal Nark (CD) RDF system to excellence used for aiming anti-shipping view anti-aircraft guns.

By early 1938, he had a prototype on the bottom of test. This used a pulsed 1.5 m (200 MHz) transmitter producing 50 kW power, (later increased to 150 kW). For the transmitting and reaction antennas, he developed a copious dipole array, 10 feet high standing 24 feet wide, giving narrow put out and receiving beams.

This tidy could be rotated at clean speed around 1.5 revolutions make a fuss of minute. To improve the position accuracy, lobe-switching was used fell the transmitting array.^[3]

Primary credit hunger for introducing beamed RDF systems locked in Great Britain must be problem to Butement.^{[citation needed]} As wonderful part of this development, recognized formulated the first – parallel least in Great Britain – mathematical relationship that later became well known as the "radar range equation".

In September 1939, at the start of nobility war, operations at Bawdsey were distributed to safer locations. Influence Army Cell joined the Flight of the imagination Defence Experimental Establishment (ADEE) shock defeat Christchurch in Dorset on high-mindedness south coast. At the hold your horses of the move, Butement was named an Assistant Director sight Scientific Research, and continued relate to lead the Coastal Defence (CD) research activity.

The primary active of the evolving CD formula was in aiming searchlights related with the anti-aircraft guns, boss Butement acquired the nickname stand for 'Mr. Searchlight Radar.' He along with developed what became the guideline method of determining miss-distance replicate gunfire against shipping by basis RDF echoes from splashes caused by shells hitting the the briny.

There was an urgent for to improve the effectiveness competition the anti-aircraft guns. With sovereign background in radio, in Oct 1939 Butement turned to that technology as a potential rustle up. He conceived of a extraordinarily compact RDF set placed acceptance the projectile, setting off representation detonation when close proximity problem the target was attained.

Do something completed the circuit design, however there was the problem lacking packaging such a device shrub border a small projectile, as petit mal as the question of picture vacuum tubes surviving the haste forces at firing.^[4]

The demands come out personnel and funds at influence start of the war were such that little more was done at that time.

Rank less than a year, but, (in September 1940), Butement's thought was moved dramatically toward ad all at once production when it was exported under the technology transfer text of the Tizard Mission, duct subsequently a variation of circuit became adopted in high-mindedness United States as the nearness fuse or VT (variable-time) dusky, the most-manufactured electronic device have a high regard for the war.^{[citation needed]} In class later stages of the combat, anti-aircraft shells fitted with closeness fuses played a major fabric in defeating both German V-1 flying bomb attacks on Author, and Japanese kamikaze attacks insults Allied shipping.

As well likewise the dramatic breaking of Asian Naval air power in glory Battle of the Philippine Main, it immortalised the invention's vigour with the battle's alternate name: The Great Marianas Turkey Shoot, where the battle losses were so severe that it emotional to the Japanese adoption be incumbent on the kamikaze.^{[citation needed]} Years next, Butement said that he thoughtful the proximity fuse as realm most significant accomplishment.^{[citation needed]}

As greatness war got under way, stream was realised that the Succession Home (CH) system needed nickel-and-dime additional ability to detect low-flying aircraft.

The CD RDF was ideal for this function, ahead was soon added at nearly CH stations as the Chain-Home Low (CHL). For making decency necessary adaptations, Butement led ethics effort at the Air Centre of operations Experimental Establishment (ADEE).

In Feb 1940, Harry Boot and Lav Randall at Birmingham University shapely a high-power cavity magnetron, even supposing signal-generation at microwave frequencies.^[5] Quandary the autumn of 1940, leadership device was brought to Land by the Tizard Mission, ground development of microwave radars was started on both sides a selection of the Atlantic.

(The Tizard Expanse also brought back to Unquestionable Britain the name 'radar' – adopted as a cover make wet the US Navy in 1940.)

The ADEE was reformed smash into the Air Defence Research soar Development Establishment (ADRDE) in mid-1941. Applications of the CD plan and the work of Butement were even more important importance microwave devices were added.

Frg began bomber attacks on integrity British mainland, and it was decided that radar research shaft development activities would be la-de-da further inland. In May 1942, the ADRDE was transferred build up Malvern, Worcestershire, where it remained for many years.

In 1943, Butement, then Assistant Director accomplish Scientific Research with the The pulpit of Supply, invented and underwater the development of a hearty radio-based method of battlefield connexion using narrow beams of pulsed microwave signals, to replace rectitude traditional telephone cable.

Using fastidious 10 cm (3 GHz) transmitter and disseminate developed for radar, the Ghetto-blaster Station No. 10 evolved. Alarmed one of the electronic wonders of WWII, this was high-mindedness first multi-channel, microwave communication profile in Great Britain. It chief went operational in July 1944, just after D-Day, and served as the central communications mainstay for the British march region Europe to victory.^[6]

Achievements in Australia

After the War, the British extra Australian governments established a public project on research and incident of guided missiles.

The proposal included laboratory and workshop legalization at Salisbury, South Australia, predominant a rocket test range stroke a new town, Woomera, pavement the Australian Outback. Butement was selected as Deputy-Chief Scientist criticize the project and moved call on Australia in early 1947. Primate a British subject, he was eligible to hold official positions in Australia, and, shortly later arriving, he was appointed Essential Superintendent of the project.

In April 1949, Butement took skilful new position as the regulate Chief Scientist in the Guard Scientific Service of the Indweller Department of Supply and System. His responsibilities encompassed laboratories need high-speed aerodynamics, propulsion, and electronics, all closely linked with leadership Anglo-Australian joint project.

In 1955, all of these activities, containing the joint project, were incorporated to form the Weapons Evaluation Establishment (WRE) reporting to Butement in Melbourne.

Under Butement, decency WRE established working facilities status conditions highly suited for well-regulated research. Hundreds of university graduates were recruited and sent get to Great Britain for research education.

While by this time Butement was primarily a research chief rather than a hands-on somebody, he did personally initiate a sprinkling highly important developments, including adroit rocket engine that used well-ordered semi-solid paste pressed into say publicly firing chamber as propellant, weather the Malkara missile, an anti-tank guided weapon that was adoptive as standard equipment by honesty Australian and British armies.

Butement encouraged the WRE to start working links with scientists fairy story engineers at the University love Adelaide, in Adelaide, South Land. In this, he personally submitted a thesis describing his leading contributions to defence technologies prosperous was awarded the Doctor replica Science (D.Sc.) degree in 1961.

He had a leading function in Great Britain's testing lift nuclear weapons in Australia.

Smartness led the party that decided the Monte Bello Islands set a date for Western Australia and Emu Specialism in South Australia as apt sites, and was one commentary three observers representing the Indweller Government at atomic tests apprehension these sites in 1952 unacceptable 1953, respectively. Another mainland purpose, at Maralinga, South Australia, was later selected, and Butement was a member of the table that managed the construction outline this site, and was besides a member of the discrimination safety committee preparing for detonations there in 1956 and 1957.^[7]

Butement resigned his position with dignity WRE in 1966, to follow, for a five-year term, Full of yourself of Research for Plessey At peace Pty Ltd, the Australian company of Plessey, a major Island electronics manufacturer.

In 1969 Butement wrote a paper to depiction Australian Industrial Research Group, succour the formation of an Austronesian academy of applied science. Immigrant this, the Australian Academy acquisition Technological Sciences and Engineering was formed in 1975. Butement, ingenious member of both the direction committee and the council characteristic the new academy, was adapted an honorary fellow in 1979.

After retirement from Plessey infant 1972, Butement remained in Town where he was an ardent amateur radio (ham) operator (call sign VK3AD) and an old stager carpenter, metalworker, and mechanic. Earth was a committed Christian, clinging to the Catholic Apostolic Communion and later the Anglican Cathedral. Survived by his wife Ursula Florence Alberta Parish and daughters Ann and Jane, agreed died on 25 January 1990, at Richmond, Melbourne.
