Ronald Hugh Barker whilst less publicly known than contemporaries such as Alan Turin (theoretical computing), Tommy Flowers (Colossus) or Alec Reeves (pulse-code modulation) he played a key pioneering role in the early development of British digital communications. Working at the Signals Research and Development Establishment (SRDE), he was instrumental in the practical applications of pulse-code modulation, particularly in telemetry for guided weapons and early digital radar but most notably for the invention of the Barker code in 1953. Barker code remains in use for synchronisation in radar, telemetry systems and digital communication processing in many applications. His work also included early applications of pulse-code modulation anticipated features of modern air traffic control systems, speech encryption and rotary encoders.

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.

PCM 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.
