Martin Ryle graduated from Oxford in 1939 with a degree in Physics.  He joined the radar team and worked on aerial design for airborne radars.  He later worked on electronic countermeasures and helped plan the D-Day spoof attack. 

At the end of the war he received a fellowship at the Cavendish Laboratory to start an investigation of the radio emission from the Sun, which had recently been discovered accidentally by Stanley Hey with radar equipment.  Martin Ryle became one of the founding fathers of radio astronomy. 

He received a Nobel prize for his work in radio astrophysics and also became Astronomer Royal.
