EMI and Alan Blumlein were not directly responsible for the invention of radio direction finding (RDF) or radar (RAdio Detection And Ranging), as it would eventually be known. They did however, play an increasingly important role in the development and application of certain elements that were used in the original form of the invention, as well as the improvement and refinement of H2S, one of the most widely used forms of the device.
