This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in this area of study. The RCS estimation of phased array including the mutual coupling effect is also presented in detail in the book. The active RCS reduction is carefully touched upon through the performance of phased arrays, sidelobe cancellers and mitigation of multipath effect. Providing information on various adaptive algorithms like least mean square (LMS), recursive least square (RLS) and weighted least square algorithms, the authors also mention the recent developments in the area of embedded antennas, conformal load bearing antenna, metamaterials and frequency selective surface (FSS) based RCS reduction.

This book presents a comprehensive review of plasma-based stealth, covering the basics, methods, parametric analysis, and challenges towards the realization of the idea. The concealment of aircraft from radar sources, or stealth, is achieved through shaping, radar absorbing coatings, engineered materials, or plasma, etc. Plasma-based stealth is a radar cross section (RCS) reduction technique associated with the reflection and absorption of incident electromagnetic (EM) waves by the plasma layer surrounding the structure. A plasma cloud covering the aircraft may give rise to other signatures such as thermal, acoustic, infrared, or visual. Thus it is a matter of concern that the RCS reduction by plasma enhances its detectability due to other signatures. This needs a careful approach towards the plasma generation and its EM wave interaction. The book starts with the basics of EM wave interactions with plasma, briefly discuss the methods used to analyze the propagation characteristics of plasma, and its generation. It presents the parametric analysis of propagation behaviour of plasma, and the challenges in the implementation of plasma-based stealth technology. This review serves as a starting point for the graduate and research students, scientists and engineers working in the area of low-observables and stealth technology.

The design and development of low radar cross section (RCS) phased array has been a challenging subject in stealth technology. The frequency selective surface elements act as absorbers in specific frequency band and facilitate gain enhancement and reduction of antenna RCS. This book presents a comprehensive EM design and analysis of such low-profile patch arrays with high impedance surface-based ground plane. It explains how to determine radiation mode RCS of low-profile antenna arrays with arbitrary configurations. Detailed descriptions of design, workflow of determining radiation and scattering behavior of antenna arrays have been supported with schematics, tables, and illustrations. Aimed at engineers and researchers for RCS, antenna engineers and graduate students in electrical engineering and electromagnetics, it • Discusses both radiation and scattering features of both planar and conformal HIS-based low profile antennas • Describes the theoretical background, design, simulations and analysis of low RCS phased array in detail • Presents the physics behind the resultant radiation and scattering characteristics of designed antenna array • Helps readers understand design and analysis of low RCS antenna array without any degradation in its radiation performance • Includes figures, schematics and illustrations to provide comprehensive descriptions of both radiation and scattering characteristics of phased arrays of different configurations

Methods of realizing the load impedance required for radar cross section control of conducting bodies are discussed. It is shown that passive loading, using frequency-dependent dielectric/magnetic materials in a radial or coaxial line, requires a frequency dependence which is not exhibited by any known material. A number of active synthesis approaches are examined, with emphasis on those using the Negative Impedance Converter (NIC). Experimental results are given for a particular NIC realization operating in the 5 - 10 MHz range; the circuit is shown to be capable of producing the load impedance required for a cross-section reduction of 13dB or more over a 2:1 bandwidth.

The leading text and reference on radar cross section (RCS) theory and applications, this work presents a comparison of two radar signal strengths. One is the strength of the radar bean sweeping over a target, the other is the strength of the reflected echo senses by the receiver. This book shows how the RCS "gauge" can be predicted for theoretical objects.

Prediction, reduction, and measurement of electromagnetic scattering from complex three-dimensional targets is the primary emphasis of this text, developed by the author from courses taught at the Naval Postgraduate School. The analysis methods discussed focus on physical optics and numerical solutions to Maxwell's equations (the method of moments and finite-difference solutions) as they apply to radar cross section. Numerous examples have been included to illustrate the application of important methods and concepts. Written as an instructional text, this book is recommended for upper-level undergraduate and graduate students. It is also a good reference book for engineers in industry.

The post-Cold War era has many implications for the way U.S. military forces will be sized, equipped, and balanced. This analysis seeks to shed light on whether other nations will attempt to increase their emphasis on airpower or instead try to challenge the United States using other means.

This unique book features 37 full-length, peer-reviewed versions of papers presented at the First Los Alamos Symposium on Ultra-Wideband Radar. The purpose of the symposium was to offer an open, unbiased forum where researchers in areas connected to ultra-wideband radar (UWBR) could present results of their work and exchange ideas. The papers published from the proceedings illuminate the breadth and depth of the topic and cover seven general areas: fundamental electromagnetic theory; computational electromagnetics and code development; signal propagation, scattering, and reception; new technologies, advanced arrays, and imaging; signal processing and radar systems; and applications and testing. The book will provide stimulating reading for scientists, engineers, managers, and students working with UWBR.

This Note addresses near-term development issues for an emerging class of weapons--long-range conventional missiles (LRCMs), defined as missiles capable of attacking targets with conventional (nonnuclear) munitions at ranges in excess of 500 kilometers. The author identifies useful roles for the LRCM and determines that technologies beyond those of the Tomahawk are both necessary and available. He recommends that the Navy focus its near-term development on an upgraded Tomahawk Block IV, while the Air Force moves toward a new LRCM design. He finds that LRCMs are fiscally affordable, and arms control regimes are being developed that address their political costs. However, institutional concerns may be the major stumbling block to LRCM development. Data and support systems needed for operating LRCMs are not currently available and will require institutional changes in the services and the intelligence community. The author makes recommendations for future technology and support policy decisions.
