Available in PDF, EPUB and Kindle. Book excerpt: "This report presents the results of a study of the many features of generic missile configurations which control their radar backscattering cross-section. First, the radar cross-section as a function of aspect angle is determined for a simple right circular cylinder in a plane which contains the cylinder axis. This result obtained by the "relative-phase" method (see Report No. 70), is compared with measured data obtained at 9.8 GHz which was reported in the literature. Excellent agreement was obtained between the theoretical calculations and the available experimental data."--Introd.

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.

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.
Download or read book Plume Effect on Radar Cross Section of Missiles at HF Band written by and published by . This book was released on 2005 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Radar Cross Section of missiles at HF band is affected by the presence of the missile plume. In fact, although the plume is transparent at the microwave frequencies, it reflect almost the totality of the energy at the HF band. In this paper we evaluate the effect of the missile plume on its Radar Cross Section (RCS) at the HF band. In order to achieve the goal we: 1) verify that the missile plume can be physically represented by a plasma through a chemical analysis of the combustion; 2) define the time-varying non-linear differential equation that rules the electron density equilibrium in the plume; 3) solve the time-varying non-linear differential equation in order to evaluate the length of the plume that contributes to the RCS calculation; 4) evaluate the RCS of the missile+plume by means of the Method of Moments (MoM). As a numerical case, the application of both a surface and sky wave Over the Horizon (OTH) radar has been considered. Specifically, the RCS (as a function of the incidence angle) of the missile during the boost phase trajectory has been evaluated.

Download or read book Development of Code for a Physical Optics Radar Cross Section Prediction and Analysis Application written by Filippos Chatzigeorgiadis and published by . This book was released on 2004-09-01 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significance of the Radar Cross Section (RCS) in the outcome of military engagements makes its prediction an important problem in modern Electronic Warfare. The POFACETS program, previously developed at the Naval Postgraduate School (NPS), uses the Physical Optics method to predict the RCS of complex targets, which are modeled with the use of triangular facets. The program has minimum computer resource requirements and provides convenient run- times. This thesis up-graded, enhanced and expanded the functionalities and capabilities of the POFACETS program. The new functionalities were implemented by upgrading the Graphical User Interface and model database, allowing the creation of models with an unlimited number of facets, providing capabilities for the automatic creation of models with standard geometric shapes, allowing the combination of existing target models, providing capabilities for sharing target models with commercial CAD programs, and creating new display formats for RCS results. The new computational capabilities include the development of a user-updateable database of materials and coating that can be applied to models in one or multiple layers, and the computation of their effects on the models' RCS. Also implemented are the computations of the ground's effect on the RCS, and the exploitation of symmetry planes in models, in order to decrease run-time for RCS prediction.

Available in PDF, EPUB and Kindle. Book excerpt: "An F-16A Math Model formulation and computer programs were developed to determine the radar cross-section of "generic jet-fighter aircraft. The analysis made use of about eight discrete scattering sources including prolate spheroids, flat circular and retangular [i.e. rectangular] plates, and cylinder edges. Using the theoretical scattering descriptions for these sources, two different RCS versus aspect angle characteristics were computed. These distinctly different RCS plots were obtained through use of (a) the "relative-phase", and (b) the "random-phase" methods of summing the individual scatterer contributions."--Conclusions.
Download or read book Radar Propagation and Signature Analysis for Maritime Engagement Scenario Antiship Missile Simulations written by and published by . This book was released on 1995 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part of this report describes the regeneration of ship radar cross section (RCS) data with lookup tables, which are used to store raw RCS, smoothed RCS, & scintillation data of a ship RCS. The second part examines sea clutter models and describes a method of generating clutter maps. The effects of phase interference (glint & scintillation), multipath, and meteorological effects on radar propagation for one way paths, relevant to software simulation, are investigated. Sea clutter was found to most frequently follow certain probability distributions, depending on sea state, radar wavelength, & grazing angle. An efficient method of generating numerous statistical distributions for clutter is introduced. This algorithm, along with the clutter map process, allows the simulation user to alter weather, multipath, & target data as discrete cells over the entire radar coverage zone.
