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.
Career timeline
- 1926-31 study of radio telecommunications at the Moscow Power Engineering Institute, dissertation in engineering science.
- 1931-41 worked at the MEI as engineer, scientific assistant, laboratory director and lecturer.
- 1941-44 worked as developer in the telecommunication industry.
- 1944-80 full professor at the MEI.
- 1953-87 deputy director and since 1954 director of the institute for radio technology and electronics at the Russian Academy of Science (IRE / RAS).
- 1964 Lenin Prize [1]
- 1970-88 vice-president of the RAS; since 1988 adviser of the presidium.
Achievements
He is mostly known for having discovered, independently of others (e.g. Edmund Whittaker, Harry Nyquist, Claude Shannon), the sampling theorem in 1933. [2] 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. [3] 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 led the first probe of the planet Mercury with radar. [4][5][6]
