Vladimir Kotelnikov

Vladimir Aleksandrovich Kotelnikov (Russian "Владимир Александрович Котельников", scientific transliteration "Vladimir Alexandrovič Kotelnikov", September 6 1908 in Kazan – February 11 2005 in Moscow) was an information theory and radar astronomy pioneer from the Soviet Union. He was elected a member of the Russian Academy of Science, in the Department of Technical Science (radio technology) in 1953.

Achievements

He is mostly known for having discovered, independently of others (e.g. Edmund Whittaker, Harry Nyquist, Claude Shannon), the sampling theorem in 1933. [Kotelnikov VA, "On the transmission capacity of "ether" and wire in electrocommunications", [http://ict.open.ac.uk/classics/1.pdf (English translation, PDF)] , Izd. Red. Upr. Svyazzi RKKA (1933), Reprint in " [http://www.ieeta.pt/~pjf/MSTMA/ Modern Sampling Theory: Mathematics and Applications] ", Editors: J. J. Benedetto und PJSG Ferreira, Birkhauser (Boston) 2000, ISBN 0-8176-4023-1] This result of Fourier Analysis was known in harmonic analysis since the end of the 19th century and circulated in the 1920s and 1930s in the engineering community. He was the first to write down a precise statement of this theorem in relation to signal transmission. He also was a pioneer in the use of signal theory in modulation and communications.

He is also a creator of the theory of optimum noise immunity. [Kotelnikov VA, "The Theory of Optimum Noise Immunity" (monograph), Russia 1956, US 1959] He obtained several scientific prizes for his work in radio astronomy and signal theory. In 1961, he oversaw one of the first efforts to probe the planet Venus with radar. In June 1962 he lead the first probe of the planet Mercury with radar. [cite journal |first=J.
