Scientific results

In 1962, he founded the well-known scientific school on multichannel analysis and digital antenna arrays[2]. The theory of multichannel analysis that was developed by him considers the methods of determination of the angular coordinates of sources as functions of the angular distances between the sources and the phase and energy relations between signals and gives the basis for the functional schemes of units realizing the theoretical conclusions. The determination of the parameters of sources is carried on by the direct solution of systems of high-order transcendental equations describing the response function of a multichannel analyzer[3]. In this case, the super-Rayleigh resolution of the sources of signals is ensured[4]. The difficulties arising at the solution of the transcendental systems of high-order equations were overcome by V. A. Varyukhin by means of the “separation” of the unknowns, at which the determination of angular coordinates is reduced to the solution of algebraic equations, and the complex amplitudes are found by the solution of the linear systems of equations of the N-th order[4].

The Interdepartmental scientific-technical meeting organized in 1977 by the Scientific Council of the USSR Academy of Sciences on the problem “Statistical radiophysics” (Chairman — Academician Yuri Kobzarev) dated officially the start of the studies performed under the guidance of V. A. Varyukhin in the trend of digital antenna arrays by 1962 and recognized the priority of Varyukhin’s scientific school in the development and practical realization of the theory of multichannel analysis[2].

In the subsequent years, V. A. Varyukhin supervised a number of theoretical works realized in several experimental radar stations with DAAs which were successfully tested on testing sites[5].

08.03.1942 — 05.08.1942 — commander of a radiostation of the 927-th separate signal battalion of the 96-th infantry division;

05.08.1942 — 11.01.1943 — commander of a radioplatoon, Stalingrad (Don) front;

11.01.1943 — 28.04.1943 — wound, medical treatment at the evacuation hospital No. 3755;

28.04.1943 — January of 1944 — commander of a radioplatoon, Ural military district;

January of 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[6].

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 (Kiev).
