This is the only book focused on the complete aspects of RF Stealth design!
Introduction to RF Stealth is the first to present and explain first order methods for the design of active and passive stealth properties. Everything from Electronic Order of Battle to key component design is covered.
It is a “How to” allowing estimation of RCS, emitter interceptability, IR signature with speed, emitter footprints, terrain obscuration and target visibility, ambient spectra, ambient pulse density, detection performance, antenna, filter and pulse compression sidelobes, emitter location accuracy, stealthy pulse compression design, stealthy antenna design, signal processor performance, and more. Unique compilations of the leading parameters of many emitters and interceptors are included, as is analytical software for each chapter.
Introduction to RF Stealth provides a new generation of designers with a firm and proven basis for new developments and to allow buyers of stealth technology to separate the charlatans from serious engineers.
