Download or read book Scattering Characteristics of Aerial and Ground Radar Objects written by Oleg I. Sukharevsky and published by CRC Press. This book was released on 2024-06-24 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents computations for various types of aerial and ground objects. It contains a brief explanation of the theoretical calculation methods used for obtaining scattering characteristics of these objects. It provides working examples for the analysis of electromagnetic wave scattering processes by different objects. Scattering Characteristics of Aerial and Ground Radar Objects is divided in two sections. The first section includes scattering characteristics for different aerial objects: aircrafts, helicopters, transport and passenger airplanes, unmanned aerial vehicles, and missiles. The second section contains data about scattering for many ground objects such as tanks, surface-to-air missile systems, ground radars, and other military objects. In total, the book contains actual data for 63 aerial objects (fighters, attack aircraft, bombers, long-range radar detection aircraft, transport aircraft, helicopters, unmanned aerial vehicles, and cruise missiles) and 18 ground objects, among which are anti-aircraft missile systems and tanks. This book contains data obtained by computations such as circular diagrams of radar backscattering; mean and median radar cross section values of various objects; probability distributions of echo signal amplitude given various parameters of illumination and various kinds of underlying surfaces (for ground objects). Also, as an example, the scattering characteristics for one surface ship are given. This book will be a valuable reference for scientists, engineers, and researchers of electromagnetic wave scattering, computational electrodynamics, and those working on radar detection and recognition algorithms for aerial and and ground radar targets.

This book was released on 2007-02-09 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first complete and comprehensive description of the modern Physical Theory of Diffraction (PTD) based on the concept of elementary edge waves (EEWs). The theory is demonstrated with the example of the diffraction of acoustic and electromagnetic waves at perfectly reflecting objects. The derived analytic expressions clearly explain the physical structure of the scattered field and describe in detail all of the reflected and diffracted rays and beams, as well as the fields in the vicinity of caustics and foci. Shadow radiation, a new fundamental component of the field, is introduced and proven to contain half of the total scattered power.

Available in PDF, EPUB and Kindle. Book excerpt: Solutions are obtained for the scattering of an incident plane electro-magnetic wave by each of the following perfectly conducting objects: (a) an infinite circular cylinder having an attached sector, which, in the limiting case of zero sector angle, becomes a circular cylinder having a fin, (b) an infinite circular cylinder having two coplanar fins, which, in the limiting case of zero cylinder radius, becomes a strip, (c) a sphere having a fin, which, in the limiting case of zero sphere radius, becomes a circular disc. In each problem, the scatterer is described by sections of constant-coordinate surfaces and the space surrounding the scatterer is partitioned into several regions. The electromagnetic field in each region is expanded in a complete set of Hansen vector wave functions with unknown expansion coefficients. These sets of expansion coefficients are then determined by satisfying the boundary conditions. A review of scattering by the circular cylinder and sphere is also presented. Numerical results are obtained for scattering by the one-finned cylinder, the finned sphere, and circular disc. For the one-finned cylinder and the finned sphere, the results show the effect of the fin on the back scattering by the cylinder and the sphere, respectively. In the case of the circular disc, the results for the back-scattering radar cross section agree with the values given by the solution of W. Andrejewski and that of physical optics. (Author).

Download or read book On the Scattering and the Modification of Scattering of Waves from a Long Wire written by Chin-Lin Chen and published by . This book was released on 1968 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of the scattering of waves by a long, thin metallic wire is studied. The Wiener-Hopf technique is used to solve the resulting integral equation. In Part I of this report, the case of a plane wave, with arbitrary angle of incidence, impinging upon an unloaded wire is considered. Explicit and rather simple expressions for the induced current, the far field pattern and the back-scattering cross sections are obtained. Numerical results are in reasonable agreement with existing experimental data. The modification of the scattering of normally incident plane waves by a loaded wire is investigated in Part II. The result shows that for short wires, the back-scattering cross sections may be modified effectively by central impedance loading, while for long wires, the modification is rather difficult to achieve. To nullify the back-scattering cross section, it is necessary to use active loading, if kh> 3.6. A physical explanation is also presented.

Download or read book High Frequency and Pulse Scattering written by Allan D. Pierce and published by Academic Press. This book was released on 2013-10-22 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Frequency and Pulse Scattering investigates high frequency and pulse scattering, with emphasis on the phenomenon of echoes from objects. Geometrical and catastrophe optics methods in scattering are discussed, along with the scattering of sound pulses and the ringing of target resonances. Caustics and associated diffraction catastrophes are also examined. Comprised of two chapters, this volume begins with a detailed account of geometrically based approximation methods in scattering theory, focusing on waves transmitted through fluid and elastic scatterers and glory scattering; surface ray representations of scattering by shells and other smooth objects; and caustics and associated diffraction catastrophes. The second chapter deals with the relation between sound pulses and the vibrational spectra of elastic submerged objects. The theory of the scattering of sound pulses from elastic and impenetrable objects is described, together with the theory of surface wave pulses. Target resonances and the singularity expansion method are also analyzed. This book will be of interest to physicists.
