Squadron Leader Leonard George Chapman (28 March 1910 – 25 July 1975) was an inventor, radio engineer and Royal Air Force officer. While serving in the Royal Air Force he invented the 'Chapman Method' in 1937–1938. This method accurately determines the location of an object from the time difference of arrival of a signal (possibly radio echo) emitted from that object to three or more receivers. A method commonly used in civil and military surveillance applications, and also known as Multilateration. Thus it has been suggested that Chapman be nominated as the father of Multilateration.
