The 2nd World War area looks at the development of Radar and how this helped to win the Battle of Britain. In 1935, in what is known as the “Daventry Experiment”, Watson-Watt demonstrated that radio waves could be used to detect Aircraft. Following the experiment the government funded the development of a Radar System which could be used to defend the United Kingdom. The system developed was the Chain Home system.
Early Radar Development
In the 2nd World War room we have examples of the type of RADAR which would have been used. The first RADAR was the Chain Home system and it had its limitations.
Firstly, being a static RADAR, it was limited to how much area could be covered. This was addressed by putting the RADARs close together around the coast and also using the Royal Observer Corps to spot the aircraft after they had flown over the coast.
Secondly the RADAR was not very accurate. This was addressed by taking inputs from three RADARs and using a filter table to correlate the plots. Come on the talk and learn how the filter table worked. The Filter board is modelled on the one at Bentley Priory.
To learn more join our talk. The talks are given throughout the day. The times will be announced over the tannoy.
