The multielement systems have been widely used in many fields of
astron omy and radio science in the last decades. This is caused by
the increasing demands on the resolution and sensitivity of such
systems over the wide range of the electromagnetic wavelengths,
from gamma up to radio. The ground-based optical and radio
interferometers, gamma-ray and X-ray or bital telescopes, antenna
arrays of radio telescopes and also some other radio devices belong
to scientific instruments using multielement systems. There fore,
the current problems of the optimal construction of such systems,
or precisely, those of searching for the best arrangement of the
elements in them, were formulated. A rather large number of
scientific papers, including those of the authors, is devoted to
these problems, and we believe that the time has come to integrate
the basic results of the papers into the mono graph. The offered
book consists of three parts. The first part is concerned with the
optimal synthesis of optical and radio interferometers of various
types and purposes; the synthesis of non-equidistant antenna arrays
is con sidered in the second part; and the methods for the
construction of coded masks for X-ray and gamma-ray orbital
telescopes are expounded in the third one. Since in the text
combinatorial constructions which are little known to astronomers
are used, the necessary information is given in the appendices.
Various tables containing the parameters of the systems consid ered
are also represented."
