INTRODUCTION
The Radar Technology Encyclopedia is a joint product of
leading United States and Russian radar experts with decades
of experience on design, development, and test of state-of-
the-art radar systems and technology. The Encyclopedia cov-
ers the entire field of radar fundamentals, design, engineering,
systems, subsystems, and major components. It contains
about 5000 entries, each giving the depicted term definition,
and, if applicable, the standard notation, brief description,
evaluation formulas, relevant block diagrams, performance
summary, and a reference to the literature in which the more
detailed information is available. The purpose is to provide,
in a single volume, the reference material for researchers and
engineers in radar and related disciplines, representing the
most modern information available in both the former Soviet
Union and in the West. It includes an extensive bibliography
of sources from both regions. This bibliography covers practi-
cally all monographs and textbooks in radar and related sub-
jects published after World War II in English (in the U.S.A.
and England) and Russian (in the former Soviet Union) lan-
guages that covers the overwhelming majority of the world-
wide library of radar books.
The Encyclopedia format is alphabetical by subject. It
consists of top-level articles, which are identified with bold
capital letters (e.g., MAGNETRON), and, if applicable, are
followed by subarticles, which are identified in lowercase
bold (e.g., rising-sun magnetron). The top-level articles are
arranged in the way so the key word (typically, a noun) deter-
mines its alphabetical position (e.g., microwave antenna is
cited as ANTENNA, microwave, radar targets as TARGET,
radar, data smoothing as SMOOTHING, data). Subarticles
within a top-level article are given in a conventional word
order typically used in literature and alphabetically arranged,
for example:
AMPLIFIER, microwave
amplifier-attenuator
amplifier chain
aperiodic amplifier
backward-wave tube amplifier
balanced amplifier
bandpass amplifier
and so forth.
The subarticles are alphabetized without regard to
whether the qualifying adjective precedes or follows the main
word: broadband antenna precedes antenna control.
Within each article and subarticle, if applicable, the
cross-reference to another subarticle is indicated in lower-
case bold, e.g.:
“The RCS of this type of clutter is calculated using the
volume of the clutter cell Vc and the volume reflectiv-
ity h
v (see volume clutter). “
That subarticle is found alphabetically within the same top-
level article, e.g., CLUTTER. If the cross-reference refers to
another top-level article, then the name of this article is given
in capital letters. For example, a reader is referred to an article
NOISE, and will find that article alphabetically under N.
Parentheses in the name of an article or subarticle mean
that the word is optional. For example, phased array
(antenna) means that the term is used both as phased array
or phased array antenna. Square brackets mean that the
word in the brackets can be used instead of the previous one.
For example, bed of spikes [nails] ambiguity function
means that the term is used as bed of spikes ambiguity func-
tion or bed of nails ambiguity function.
For definitions of terms, extensive use has been made of
IEEE Standard Dictionary of Electrical and Electronics
Terms and IEEE Standard Radar Definitions. The standard
definitions reproduced from these dictionaries and other
acknowledged sources are put into quotes. The Encyclopedia
does not contain separate articles with the description and
performance of concrete radar stations and facilities, because
even brief description of the major radars developed through-
out the world requires to provide additional volume as thick
as this one. This information is systematized in Jane’s Radar
and Electronic Warfare Systems, updated and issued annually,
and the Encyclopedia does not duplicate this material. How-
ever, where applicable, extensive examples of modern radars
are provided.
xii
Each article and subarticle contains references, primarily
to textbooks, which are listed alphabetically by author in the
Alphabetical Bibliography at the end of Encyclopedia. The
combination of the surname of the first author and a year of
edition identifies the cited book:
Ref.: Skolnik (1980)
refers to the book listed in the bibliography as:
Skolnik, M. I., Introduction to Radar Systems, McGraw-
Hill, 1980;
and the brief reference:
Ref.: Barton (1969)
identifies the book listed with both authors and two editions
or publishers:
Barton, D. K., and Ward, H. R., Handbook of Radar Mea-
surement, Prentice-Hall, 1969; Artech House, 1984.
In rare cases where there is no applicable textbook, reference
is made to a professional journal article. Typically, each arti-
cle is followed by references to the major current books, as
listed in the Alphabetical Bibliography, and for the readers
interested in a full bibliography on a corresponding subject
the Bibliography by Subject is provided. It contains a full bib-
liography list of the identifiable radar and radar-related books
published during the last 50 years and is arranged in 35 sec-
tions by subject. Within each section the books are given in
chronological order, and alphabetically by author within one
year. At the end of Encyclopedia is a list of the most common
radar abbreviations and acronyms.
The author of each article and subarticle is identified by
the corresponding initials following the entry, when that entry
exceeds a few lines of definition (see About the Authors). The
original generation of the list of entries, compiling of the Bib-
liography, and final editing of Encyclopedia material was
done by David K. Barton and Sergey A. Leonov.

Use of Hypertext Links
In this electronic edition of the Radar Technology Ency-
clopedia, hypertext links have been added to transfer rapidly
from one article to a related or referenced subject. The words
or phrases from which links can be exercised appear in blue
text. Clicking on any blue entry initiates an immediate trans-
fer to the related entry. The program keeps track of the history
of these transfers, and the reader can retrace steps by clicking
in either the right or left page margins.
