Royal Navy Metric Warning Radar, 1935–45

  • J. S. Shayler

Summary

Admiralty decision to investigate RDF applications independently — provisional Staff Requirement for warning set against aircraft and ships, October 1935. Early experimental work on 4-m wavelength disappointing — reorganisation of radar research under Horton in 1937. New development on 7.5-m for shipborne installation — choice of horizontal polarisation — successful development of Type 79. Fitting in Sheffield and Rodney in autumn 1938 — further improvements leading to Type 79Z, first installed in AA cruiser Curlew in August 1939. Improvements in silica-envelope transmitter valves giving higher peak power — introduction of ranging panel, Type 279, in September 1940 — the anti-DF facility — development of common Transmit/Receive operation in Type 279B. Anti-jamming filter — discovery of effect of galactic noise on long metre-wave radars. Technique for height determination — development of performance meter — development of improved warning set Type 281 for aircraft and surface targets in the 90 MHz band. Development of new high-power 90 MHz transmitter valve at Signal School — development of split-lobe DF to give improved bearing accuracy. Introduction of common Transmit/Receive operation into Type 281B.
