Book by Knott, Eugene F., Shaeffer, John F., Tuley, Michael T.

Radar cross section (RCS) is a comparison of two radar signal strengths. One is the strength of the radar beam sweeping over a target, the other is the strength of the reflected echo sensed by the receiver. This book shows how the RCS gauge can be predicted for theoretical objects and how it can be measured for real targets. Predicting RCS is not easy, even for simple objects like spheres or cylinders, but this book explains the two exact forms of theory so well that even a novice will understand enough to make close predictions. Weapons systems developers are keenly interested in reducing the RCS of their platforms. The two most practical ways to reduce RCS are shaping and absorption. This book explains both in great detail, especially in the design, evaluation, and selection of radar absorbers. There is also great detail on the design and employment of indoor and outdoor test ranges for scale models or for full-scale targets (such as aircraft). In essence, this book covers everything you need to know about RCS, from what it is, how to predict and measure, and how to test targets (indoors and out), and how to beat it.

This reference describes techniques for controlling the RCS of targets, provides analytical methods for estimating RCS, develops models for the design of low RCS targets and antennas, and discusses several RCS enhancement techniques.

With this book practitioners responsible for analyzing, specifying or evaluating RCS imaging systems will be able to define performance limits using basic physical and mathematical principles. Information on instrumentation systems for acquiring data and two new chapters on applications of new techniques are included. The emphasis of the book is on imaging as applied to radar cross-section measurements. With it the reader will learn how to use the latest techniques to perform RCS imaging in laboratory or outdoor test ranges. This book is suitable for self-study or for use in a short course for practising engineers.

Radar and Laser Cross Section Engineering, Third Edition reflects recent developments that have found applications in both the military and civilian sectors. These developments have been fueled by growth in computer technology, signal processing techniques, and new materials that have interesting and unusual electric and magnetic behavior. Many concepts conceived decades ago have finally become a reality. In addition to new discussions in developing technical areas, more homework problems and examples have been added to this new edition. It is assumed that the reader has mastered electromagnetics at an undergraduate level. Completion of a course in antennas also is a helpful prerequisite to this book, although students without an antenna background have successfully mastered the material presented. Contents Preface 1 Radar Cross Section 2 Basic Theorems, Concepts, and Methods 3 Frequency-Domain Numerical Methods 4 Time-Domain Numerical Methods 5 Microwave Optics 6 Complex Targets 7 Radar Cross Section Reduction 8 Measurement of Radar Cross Section 9 Laser Cross Section Appendix A Notation, Definitions, and Review of Electromagnetics Appendix B Coordinate Systems Appendix C Review of Antenna Theory Appendix D Review of Transmission Lines Appendix E Scattering Matrices Appendix F Properties of Composite Materials Index Supporting Materials

Our One-Story Scaffolding Frame Set with Galvanized Scaffolding Cross Braces is designed for safe use. The scaffold frames are made of heavy-duty 16 GA and 13 GA steel tubes that can hold as much as 9920 lbs. The scaffold set creates a 5-foot-high scaffold section reinforced by galvanized steel cross braces that are protected from corrosion, increase resistance, and improve durability. You can set up scaffolding for painting, masonry, remodeling, facade work, and more. Safety is the key to working with heights, so our scaffolding equipment is blue powder coated with a textured finish that improves grip and footing when climbing the scaffold ladder or working in wet environments. Our Saferstack innovation also allows you to nest and interlock the frames for easier portability and to reduce the probability of slippage when storing. This also helps you save 30% of storage space when stacked. Our scaffold frame set meets and exceeds ANSI and OSHA standards to help you reduce the risk of worker injury. Metaltech builds and designs practical, effective, efficient, and safe work equipment for office and home use. We strive to incorporate new technology and innovation into equipment and accessories that make sense, so you can get jobs done easily and on time.
