TL;DR: In this paper, the authors show how the RCS gauge can be predicted for theoretical objects and how it can be measured for real targets, and the two most practical ways to reduce RCS are shaping and absorption.
Abstract: 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.

TL;DR: This paper provides a survey of all the architectures that have been presented in the literature so far, using a unified description that includes optimization problem statements, diagrams, and detailed algorithms.
Abstract: Multidisciplinary design optimization is a field of research that studies the application of numerical optimization techniques to the design of engineering systems involving multiple disciplines or components. Since the inception of multidisciplinary design optimization, various methods (architectures) have been developed and applied to solve multidisciplinary design-optimization problems. This paper provides a survey of all the architectures that have been presented in the literature so far. All architectures are explained in detail using a unified description that includes optimization problem statements, diagrams, and detailed algorithms. The diagrams show both data and process flow through the multidisciplinary system and computational elements, which facilitate the understanding of the various architectures, and how they relate to each other. A classification of the multidisciplinary design-optimization architectures based on their problem formulations and decomposition strategies is also provided, a...

TL;DR: The extensively illustrated 2nd edition presents the fundamentals of the aircraft combat survivability design discipline as defined by the DoD military standards and acquisition processes.
Abstract: Second edition, still the only text of its kind and required reading for anyone involved in design of air combat vehicles. Aircraft combat survivability is now an established design discipline for U.S. military aircraft. More importantly survivability is now an essential part of the U.S. Department of Defence acquisition process. Furthermore, improving public health, safety, and survivability is now woven throughout the civil and commercial sector. From infant car seats to the design of aircraft cargo bay structures that can withstand internal bomb blasts, the US Government is establishing survivability standards. The extensively illustrated 2nd edition presents the fundamentals of the aircraft combat survivability design discipline as defined by the DoD military standards and acquisition processes. It provides the history of, the concepts for, and the assessment methodology and the design technology for the combat survivability analysis and design of fixed- and rotary-wing aircraft. UAVs, and missiles. Each chapter specifies learning objectives; stresses important points; and includes notes, references, bibliography and questions.

TL;DR: Although the bistatic radar has several interesting attributes, it is not as generally applicable as the more versatile monostatic radar because of the limited fence-type coverage and the difficulty of extracting target location information.
Abstract: This paper briefly describes some of the characteristics, capabilities, and limitations of the bistatic radar when used for the detection and location of targets such as aircraft or satellites. (A bistatic radar is one in which the receiver is physically separated from the transmitter so that the echo signal does not travel over the same path as the transmitted signal.) Among the topics discussed are the type of information available from the received signal, methods for extracting information from the bistatic radar signal, bistatic radar equation, target cross sections, and the properties of the bistatic radar fence. Throughout the paper the bistatic radar is continually compared to the conventional monostatic radar. It is concluded that although the bistatic radar has several interesting attributes, it is not as generally applicable as the more versatile monostatic radar because of the limited fence-type coverage and the difficulty of extracting target location information. An appendix is included which describes the multiple-frequency CW method for measuring distance as applied to either the bistatic or the monostatic radar.
