The Telecommunications Research Establishment was a British research facility that played a significant role in advancing telecommunications technology.
Established in 1939, the establishment was initially tasked with developing radar technology for the British military during World War II.
The team at the establishment made significant contributions to radar technology, including the development of the first operational radar system, which was used to detect and track enemy aircraft.
The establishment's work on radar technology laid the foundation for future telecommunications research, including the development of modern communication systems.

History
The Post Office Research Station at Martlesham Heath, Suffolk, was officially opened in 1975 by Queen Elizabeth II.
This marked a significant development in the UK's telecommunication sector, as the research station was designed to be a state-of-the-art facility for the advancement of post and telecommunications technology.
The move from the previous location at Dollis Hill, London, to the spacious site at Martlesham Heath, provided researchers with modern facilities and more room for expansion.
Research initially focused on telecommunications, including the System X digital exchange and early fibre optic communication systems.

Location
The Telecommunications Research Establishment was located in Malvern, Worcestershire, England. This picturesque town is nestled in the rolling hills of the Malvern Hills, providing a serene backdrop for the scientists and engineers who worked there.
The establishment was situated in a 200-acre site, which was specifically chosen for its accessibility and proximity to the nearby Malvern Hills College. This location allowed for easy collaboration between the researchers and the college's students.
The site was also home to a number of state-of-the-art facilities, including laboratories, workshops, and a large library. These resources were crucial for the researchers as they worked on cutting-edge telecommunications projects.
The establishment's location in Malvern was also convenient for commuting, with regular bus services connecting the site to nearby towns and cities. This made it easy for employees to travel to and from work.

Signal Receiving Methods
Signal receiving methods were crucial for determining a target's bearing and height. By comparing the relative strengths of signals received by each of the crossed dipoles, operators could use a Goniometer to find a null point and deduce the target's bearing.
The original transmission aerial array had four aerials, but this was later modified to three aerials. Chain Home transmitter and receiving aerials were used for this purpose.
Comparing the relative outputs of the pairs of aerials at different heights allowed operators to correct for the curvature of the earth and find the target's height. This required concentration and was a time-consuming process.
The Chain Home system was designed to give early warning of bomber raids, allowing fighter squadrons to be scrambled to intercept them.

Radar and Malvern's Secret Scientists
The scientists who came to Malvern in May 1942 were from the Telecommunications and Radar Establishment (TRE), responsible for radar for the RAF and the Fleet Air Arm.
They were young, clever men and women who lived either in a large former hotel in the centre of Malvern or were billeted with families.
None of them wore uniform, and none seemed to have any intention of joining the forces or helping the war effort, which made them despised and disliked by the local people.
Their work was top secret and couldn't be disclosed to anyone, but they were actually helping with the war effort.
The scientists worked closely with RAF Defford, and aircraft tested the latest radar equipment on the 'hidden' runways at Croome Court.
Malvern scientists were based in two main areas: the school buildings of Malvern College and Pale Manor in Malvern Link.

Secrets and Operations
The Telecommunications Research Establishment was involved in various secret operations, including the development of radar technology during World War II.
One of the most notable operations was the development of the Chain Home radar system, which was used to detect and track enemy aircraft.
The Chain Home system was a network of radar stations located along the British coastline, designed to detect and track enemy aircraft as far as 150 miles away.
This system was a game-changer in the war effort, providing early warning of incoming enemy aircraft and allowing the British military to scramble fighter planes to intercept them.
The Telecommunications Research Establishment also worked on the development of the H2S radar system, which was used to detect and track enemy aircraft at night.
The H2S system used a different frequency than the Chain Home system, allowing it to penetrate cloud cover and detect enemy aircraft even in poor weather conditions.
The H2S system was a significant improvement over the Chain Home system, providing more accurate and reliable detection of enemy aircraft.
The Telecommunications Research Establishment's work on radar technology played a crucial role in the Allied victory in World War II.
