History of RADAR
During the post-war period, British radar research continued at institutions such as the [[Signals Research and Development Establishment]] (SRDE). In 1953, engineer [[Ronald Hugh Barker]] developed a method for synchronising digital communication systems, known as the [[Barker code]]. This binary sequence improved the reliability of signal transmission in radar and telemetry applications. The code remains in use today for pulse compression in radar systems and in many other digital applications.

Following World War II, British research into radar systems continued at facilities such as the Signals Research and Development Establishment (SRDE. Among the key contributors was Ronald Hugh Barker, a physicist and engineer who played a significant role in the digital development of radar systems. His work on pulse-code modulation and digital transmission methods also contributed to early experiments in encrypted radar signals and the foundations of modern air traffic control systems.
