About this book

This book provides a solid foundation for understanding radar energy warfare and stealth technology. The book covers the fundamentals of radar before moving on to more advanced topics, including electronic counter and electronic counter-counter measures, radar absorbing materials, radar cross section, and the science of stealth technology. A final section provides an introduction to Luneberg lens reflectors. The book will provide scientists, engineers, and students with valuable guidance on the fundamentals needed to understand state-of-the-art radar energy warfare and stealth technology research and applications.

Chapter 1. Fundaments of Radar

Abstract
This chapter gives an elementary account of radar’s principles and goes over essential of radar as a detecting device. Radar was one of the elements that helped Britain in their air war against German Luftwaffe during the peak of the Battle of Britain, and they managed to survive during such invasion. The subject is simple, the methods are powerful, and the results have broad applications. Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects, and it can be used to detect aircraft, ships, spacecraft, guided missiles, or motor vehicles or even to be able to forecast the weather formations and terrain. Today with all the stealth technologies that is pushing state of new generation of fighter planes to the stage of sixth generation and new threats hypersonic objects that are flying faster than speed of sound to level 5–15 Mach number; thus, the radar warfare is taking a different innovative level.

Chapter 2. Electronic Countermeasure and Electronic Counter-Countermeasure

Abstract
The evolution of electronic warfare has been driven by the competition between electronic countermeasures (ECM) and electronic counter-countermeasures (ECCM). Electronic warfare involves not only harnessing the electromagnetic spectrum but defending against enemy use of the spectrum, and, if possible, denying their ability to use it in the first place. Since the earliest attempts at jamming radio communications, techniques have been developed to counteract enemy ECM. Today we’ll discuss how ECCM continues to evolve and shape the nature of modern warfare.

Chapter 3. Radar-Absorbent Material and Radar Cross Section

Abstract
Radiation-absorbent material, usually known as RAM, is a material which has been specially designed and shaped to absorb incident RF radiation, as effectively as possible, from as many incident directions as possible. The more effective the RAM, the lower the resulting level of reflected radio-frequency (RF) radiation. Many measurements in electromagnetic compatibility (EMC) and antenna radiation patterns require that spurious signals arising from the test setup, including reflections, are negligible to avoid the risk of causing measurement errors and ambiguities. Radar cross section (RCS) of a target is also subject of this chapter, where this phenomenon is the ratio of the radar power scattered by the target in the direction of the radar receive antenna to the power density incident on the target.

Chapter 4. Stealth Technology

Abstract
The rules of battle have changed over the entirety of military history. Tools such as technology, strategy, tactics, and weapons have been the principal elements determining what kind of rules apply to the battlefield. What can constitute to a sixth-generation fighter jet?—that is the question we should be asking ourselves since the past week. Perhaps, it might be too early to think of these questions, when even planes like Joint Service Fighter (JSF), PAK-FA, F-22, or F-35 are not even fully operational. The contemporary military rivalry is driven mostly by the ongoing military technical revolution. In particular, the weapons used on the future battlefield will play an important role in military affairs. Which weapons can play a key role in the future?
