The book is based on the "EW 101" columns in the "Journal of
Electronic Defense."  It is, in fact, the first sixty such columns,
structured into chapters and linked with additional material.

Electronic warfare (EW), as chapter one tells us, is intended to
reserve the electromagnetic spectrum for friendly use, while denying
it to the enemy.  We may be using the spectrum for communications,
such as radio, although the primary concern seems to be with remote
sensing, such as radar.  EW is not concerned with such activities as
interception of enemy communications, or the design of directed energy
weapons.  Chapter two covers basic mathematics necessary for working
with EW, such as logarithms (for working with decibel, or dB,
representations) or spherical trigonometry.  There is a very clear
discussion of antenna characteristics, uses and design considerations
in chapter three.  Chapter four does the same thing for receivers,
with an added examination of the concept of sensitivity.  Processing
of received signals is dealt with in chapter five, with a special
concentration on display for and to the user (generally a pilot or
signals officer).  Chapter six looks at the multidimensional and
multitechnology problem of the search for "threats" (as radio emitters
are known in electronic warfare circles).  "Low probability of
intercept" (LPI) signals are the topic of chapter seven, which
emphasizes the considerations in regard to spread spectrum technology. 
Various techniques for locating emitters are covered in chapter eight. 
Chapter nine deals with the many different types of jamming, and the
power calculations necessary to concepts such as "burn through" range. 
Different types, missions, and purposes of decoys are discussed in
chapter ten.  Chapter eleven examines a wide variety of considerations
involved in simulations.

As the title notes, for those interested in an introduction to the
topic, this book is an informative and interesting tutorial, readable,
and with a minimum of mathematics necessary to the topic.
