Reference excerpt

Vladimir Alekseevich Varyukhin (December 14, 1921 — July 8, 2007) was a Soviet and Ukrainian scientist, Professor, Doctor of Technical Sciences, Honored Scientist of the Ukrainian SSR, Major-General, founder of the theory of multichannel analysis, and creator of the scientific school on digital antenna arrays (DAAs).

Scientific results In 1962, he founded the well-known scientific school on multichannel analysis and digital antenna arrays. 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. In this case, the super-Rayleigh resolution of the sources of signals is ensured. 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. 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. 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.

Career Timeline

During World War II 27.09.1939 — 08.03.1942 — radio operator of the 2nd Red-Banner army of the Far-East front; 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 1944 — commander of a radioplatoon, Ural 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 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).

Worked examples

Example 1 — a first encounter with Vladimir Varyukhin

Start with the simplest possible case. Write down what Vladimir Varyukhin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vladimir Varyukhin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vladimir Varyukhin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vladimir Varyukhin

In research: Vladimir Varyukhin appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vladimir Varyukhin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vladimir Varyukhin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1921 births, 2007 deaths, Colonels of the Soviet Union, so understanding it makes those chapters shorter.
In everyday life: Look for Vladimir Varyukhin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
