Features:
- Radar cross section defined in simple terms for even novices.
- Shows how the RCS of targets can be predicted and measured.
- Describes the design, operation and characteristics of indoor and outdoor RCS test ranges.
- Presents examples of measured RCS patterns for a selection of large and small test objects.
- Discusses target shaping and design, evaluation, and selection of absorption materials.
This is the Second Edition of the first and foremost book on this subject for self-study, training, and course work.
Radar Cross Section 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, Radar Cross Section covers everything you need to know about RCS, from what it is, how to predict and measure, how to test targets (indoors and out) and how to beat it.
