Preface
More than 20 years have passed since the publication of Electronic Intelligence:
The Analysis of Radar Signals (Artech House, 1983) and Electronic Intelligence:
The Interception of Radar Signals (Artech House, 1985). Much of what those
books contained remains valid today. With this new book, I have again avoided
emphasizing specific hardware and software currently available because it changes
too rapidly. My hope is that this book remains useful for the next 20 years. This
book is partially based on my earlier works, Electronic Intelligence: The Analysis
of Radar Signals (Artech House, 1983), Electronic Intelligence: The Analysis of
Radar Signals, Second Edition (Artech House, 1993), and Electronic Intelligence:
The Interception of Radar Signals (Artech House, 1985).
It is appropriate to list those people who introduced me to the exciting field
of ELINT and who continue to provide insights and inspiration. Professor E. M.
Williams of Carnegie-Mellon University introduced me to the field. Dr. Thomas
F. Curry provided my early training. Both are now gone but often remembered.
There is no way to adequately recognize the contributions of Robert B. Shields,
my friend and business associate for more than 45 years. He always grasps the
‘‘big picture’’ and asks the right questions at the right time.
For their contributions to this book, I am grateful to Arthur Self for his work
on Chapter 4 and to Charles Estrella for his work on Chapter 6.
I am also grateful to the many people who work in ELINT and who have
shared their experiences and insights with me. This includes not only my coworkers
at Research Associates of Syracuse, Inc., but also the several thousand people who
have attended continuing education courses I have presented over the past 20
years—many for the Association of Old Crows. The struggle to answer their
questions is one of the motives in writing this book.
The continued support of my wife, Jane, and the good start in life provided
by my parents Mildred and Asa (1911–1995) were key to the creation of this book.
I am also thankful for the support of my six children, their spouses, and our 13
grandchildren. Many of them are now in their teens and approaching adulthood.
It is my hope and prayer that vigilance through ELINT and other means helps
keep them and all children everywhere in safety and freedom.
‘‘Lord God Almighty, in whose Name the founders of this country won liberty
for themselves and for us, and lit the torch of freedom for nations then unborn:
Grant that we and all the people of this land may have grace to maintain our
liberties in righteousness and peace. . . .’’
