military district; January 1944 — 12.04.1944 — commander of a radioplatoon, one of the Ukrainian fronts, 12.04.1944 — 10.07.1945 — commander of a radioplatoon (Soviet-American Operation Frantic); After of the World War II 10.07.1945 — 23.05.1951 — listener of S. M. Budennyi Military Electrotechnical Academy of Communication (Leningrad); 23.05.1951 — 18.11.1961 — lecturer at the Military Command Academy of Communication and then at S. M. Budennyi Military Electrotechnical Academy of Communication (Leningrad); 27.11.1956 – defended the dissertation for a Candidate degree (Techn. Sci.) at the Council of S. M. Budennyi Military Red-Banner Engineering Academy of Communication. Since 18.11.1961, he served at Kiev Higher Air Defense Engineering School and then was the Head of a chair at A. M. Vasilevskii Military Academy of Air Defense of the Land Forces till 1981. The significant stage of the recognition of Varyukhin's scientific results became the defense of the dissertation for a Doctoral degree (Techn. Sci.) in 1968. The distinctive feature of the theoretical trend developed by him is the maximal automatization of the process of estimation of the coordinates and the parameters of signals under conditions of their superresolution. Professor — since 1972, Honored Scientist of the UkrSSR — 1979. Since 1996 — work at the Academy of Armed Forces of Ukraine (Kyiv). Selected publications V. A. Varyuhin, S. A.
