WON’T GET FOOLED AGAIN? COMMON SOURCES OF RADAR UFOS

uring the 1930s British scientists discovered that when radio waves from a transmitter struck targets such as aircraft, ships and buildings they bounced back and could be detected by a receiver. The Air Ministry quickly began to develop a functioning early warning system that could be used to calculate the distance, direction and height of German aircraft by listening for the echoes returned from bursts of radio waves. Originally known as Radio Direction and Finding (RDF) the term ‘radar’ was adopted during WWII when the Chain Home system, built around the English coastline, was the key to the success of the RAF in the Battle of Britain.
