Dwight O. North
Dwight O. North (born September 28, 1909 in Hartford (Connecticut) , † June 26, 1998 ) was an American physicist and engineer .
North studied at Wesleyan University and Caltech , where he received his doctorate in physics in 1933. From 1934 until his retirement in 1974 he worked at RCA . First he was in Harrison (New Jersey) and from 1942 on at their newly established laboratories in Princeton .
He initially dealt with noise in vacuum tubes in the 100 MHz band as part of the development of television . During World War II , he worked on radar at the Massachusetts Institute of Technology's Radiation Lab . After the Second World War he dealt with solid state physics .
North was the first of the concept of the matched filter formalized (matched filter) and is regarded as its inventor. This happened in a secret report from RCA Laboratories in Princeton in 1943 (reprinted in Proc. IEEE, July 1963). The term matched filter comes from an independent work at Harvard Radio Research Lab in 1944 by John Hasbrouck Van Vleck and David Middleton.
North's report also contained several other concepts that later became important to radar engineers ( Rice distribution , the concept of false alarms to define a detection threshold , exploring integration before and after detection).
In 1998 he received the Golden Jubilee Award from the IEEE Information Theory Society .
