Dmitri Korolkov was born in Gomel in 1925.
In 1942 he volunteered to Red Army took
part in military operations of World War II, was wounded twice,
got demobilized in 1948.
Immediately after the graduation from the Leningrad
Polytechnical Institute he began his activity in field of radio astronomy
in the group of Pulkovo radio astronomers under the supervision of Prof.
S. Eh. Khaikin.
In 1962 Korolkov presented his thesis for the
degree of Candidate of Science ( Ph.D. ) and in 1972 he presented his Dr.Sc.
thesis in physics and mathematics.
In 1969 D. ëÏrÏl'kÏv was appointed to be
Chief Designer of radio electronic equipment for the world's largest
reflector radio telescope RATAN-600, being under construction at that time.
A gifted engineer,
a thoughtful researcher, Dmitri K. took an active part in the development
of interferometric techniques of solar observations, he was one of initiators
of the project of biggest specialized cross-line telescope.
In 1962 he
created and reduced to practice at the Big Pulkovo Radio Telescope the
most sensitive at that time broad - band straight amplification radiometer
with a parametric amplifier.
The first
observations at Pulkovo showed that the high sensivity of radiometers cannot
be implemented becase of the proper inherent radiation of the atmosphere.
The double-beam method of combatting atmospheric interferences, he
investigated in detail, appeared to be quite efficient in the case of big
area aperture antenna, when the entire atmosthere is in the near zone
for the radio telescope.
In 1977-1980 under quidance of Dmitri Korol'kov
the task of implementation of a novel promising radiometric ciruit was
performed.
He combined the cryogenic cooling of a radiometer front-end, a novel
"balanced noise-adding" radiometer design and cooling of the antenna
system with aid of simple nets that screened the proper radiation
of the radio telescope foundation, wich made it possible to achieve one
of the highest sensivity in the world.
Chief Designer
of the radio telescope RATAN-600, state prize-winner Dmitri Korol'kov
was interested in different areas of radio astronomy achieving nearly always
success in his work.
