This book brings the reader up to date on almost every aspect of modern Electronic Warfare, and is well worth reading.
But I must add two caveats. First, Schleher covers so much ground in one volume that a great deal of background material is necessarily left out. The reader needs to be reasonably familiar with military electronics and the relevant aspects of physics to understand a lot of the material presented here. Indeed,in a few places, such as the discussion in Section 8.1.1 of high-power microwave weapons, so much has been left out that I doubt whether anybody who lacks specialized knowledge of that particular topic can infer the implications of what Schleher says.
My second caveat is that, perhaps because of space limitations, the book contains essentially no material relating the great mass of technical information it provides to operational doctrine and the tactical implications of operational doctrine. Given that it's impossible to put all of the very latest-and-greatest technical innovations into every weapon and every platform (because it would cost too much, add too much weight, take up too much space, and make maintenance inordinately difficult) the choice of what to use where has to be made on the basis of how the platform or weapon is to be used, and that can only be determined by considering operational doctrine. Many engineers, and even some military personnel, tend to overlook this, so in a book like Schleher's it would be invaluable to have this relationship discussed. But it isn't.
However, I found the book fascinating and informative.
