Available in PDF, EPUB and Kindle. Book excerpt: The traveling surface wave phenomenon, a significant echo mechanism for long, smooth bodies, manifests itself in the radar cross section (RCS) pattern of realistic targets for horizontal polarization and grazing angles of incidence. Existing radar cross section models do not take this scattering mechanism into account because none of the presently available theories and methods can treat traveling waves in routine fashion (see E.F. Knott, A progression of High-Frequency RCS prediction Techniques, Proc., IEEE, Vol. 73, No. 2 pp. 252-264(Feb 1985). Analytical radar cross section models for realistic targets should include this type of scattering in their calculations. This report presents a theory and an efficient method for calculating traveling surface wave contributions on a thin rod and an ogive of arbitrary length. Rectangular flat plate radiation patterns are also briefly considered. The details and necessary expressions for predicting RCS of plates will be given in a future report, where the approach will be extended to a more complex target. The theoretical approach presented here is based on the existing concepts of antenna theory and geometrical theory of diffraction. Radar cross section patterns that include traveling wave contributions for a rectangular flat plate and a rod of equal length are calculated and compared with measurements. The theoretical results and measured data show very good agreement.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Radar and Laser Cross Section Engineering by : David C. Jenn
Download or read book Radar and Laser Cross Section Engineering written by David C. Jenn and published by AIAA (American Institute of Aeronautics & Astronautics). This book was released on 1995 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Radar Cross Section Measurements written by Eugene F. Knott and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original campus of the University of Michigan was nearly a perfect square about a half-mile along a side. A street-sized walk, appropriately called the Diag, runs diagonally across this square, connecting its southeast and northwest corners. In 1904 a new engineering building was either started or finished (I do not remember which) to house classrooms. When another engineering building was built on the expanded campus across the street from it many years later, the old building came to be known as West Engine, to distinguish it from the new East Engine. Old West Engine is (or maybe by now, was) a four-story, L-shaped structure that stood at the southeast corner of the original campus. It was built with an arch in it to straddle the Diag at the apex of the L. You walked over the Engineering Arch to get from one leg of the L to the other if you were inside the building, and you walked under it when you entered the campus from the southeast corner. Affixed to the masonry wall of the arch was a plaque I often noted in passing. It bore a quote attributed to Horace Greeley (1811-1872), who I did not know at the time was the founder, editor, and publisher of the New York Tribune. It said, simply, Young man, when theory and practice differ, use your horse sense. The suggestion seems worthy of an exclamation point instead of a period, but I do not remember if it had one.
Book Synopsis Active Radar Cross Section Reduction by : Hema Singh
Download or read book Active Radar Cross Section Reduction written by Hema Singh and published by Cambridge University Press. This book was released on 2015-03-02 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: During the Conference on Air-Sea Interaction in January 1986, it was suggested to me by David Larner of Reidel Press that it may be timely for an updated compendium of air-sea interaction theory to be organized, developed, and published. Many new results were emerging at the time, i.e., results from the MARSEN, MAS EX, MILDEX, and TOWARD field projects (among others) were in the process of being reported and/or published. Further, a series of new experiments such as FASINEX and HEXOS were soon to be conducted in which new strides in our knowledge of air-sea fluxes would be made. During the year following the discussions with David Larner, it became apparent that many of the advances in air-sea interaction theory during the 1970s and 1980s were associated with sponsor investments in satellite oceanography and, in particular, remote sensing research. Since ocean surface remote sensing, e.g., scatterometry and SAR, requires intimate knowledge of ocean surface dynamics, advances in remote sensing capabilities required coordinated research in air-sea fluxes, wave state, scattering theory, sensor design, and data exploitation using environmental models. Based on this interplay of disciplines, it was decided that this book be devoted to air sea interaction and remote sensing as multi-disciplinary activities.

Book Synopsis Estimation of the Sea Surface Radar Cross Section at HF from Second-Order Doppler Spectrum Characteristics by : D. B. Trizna
Download or read book Estimation of the Sea Surface Radar Cross Section at HF from Second-Order Doppler Spectrum Characteristics written by D. B. Trizna and published by . This book was released on 1982 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique is developed for estimating the radar cross section of the sea surface at HF (2-30 MHz) from two simple measurements made of the radar Doppler spectrum. These are: the ratio of approach/recede Bragg line energy, and the ratio of strongest Bragg line amplitude to average value amplitude of second-order backscatter at zero Doppler frequency. A nomograph is given, based on a theoretical model of second-order scatter developed by the author, which then allows one to determine the number of decibels the Bragg ocean spectral component is down from the classical Phillips asymptotic value, used here only for a reference. Comparison is made with some surface wave data for three different cases in which buoy data are available for comparison with multi-frequency radar data collected simultaneously at two different look angles. An example is also shown where such a calculation can be used to estimate the cross section of a target return existing within the same Doppler spectrum. Limitations of the technique are also discussed. (Author).
