Download or read book Broadbanding Techniques for Radomes written by P. S. Mohammed Yazeen and published by Springer Nature. This book was released on 2020-12-14 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief details various techniques employed for enhancing the transmission efficiency of radomes by modifying the radome wall configurations. These broadbanding techniques are based on inclusion of metallic wire-grids/meshes in the radomewalls, inclusion of metallic strip-gratings in the radome layers, inclusion of FSS based structures in between the radome layers and the use of inhomogeneous dielectric structures as radome wall. The volume provides detailed chapter-wise explanation of the design aspects and discusses the performance analysis of the modified radome wall configurations. It will be of interest to researchers, academicians and students working in the field of radomes.

Book excerpt: The significance of this research and development to the Air Force is that a new type of electromagnetic window panel was designed and tested that exhibited a bandwidth of 10:1 or greater. Empirical data are included on both flat panels and curved panels. A typical panel that operates from 4 GHz to 40 GHz, having 90 percent or better transmission coefficient from 0 to 60 deg angle of incidence range, is 1.5-inches in thickness. The inner and outer surfaces of the panel are either grooves or pyramids. This type panel design has excellent circular polarization characteristics, since the amplitudes of the parallel and perpendicular components are near equal and since the insertion phase delays for the two components are approximately the same. Antenna radiation pattern measurements are included that also verify the broadband characteristics of these panels. Data are also presented on a computer analysis program of transmission through an anisotropic media. The analytical results compare favorably with the measured data. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Boresight error measurements on tapered solid wall radomes have provided an experimental boresight bandwidth of 3.6%. Boresight bandwidth is defined as the frequency band where boresight error slopes are less than .01 degree/degree in any 20 degree gimbal period. Theoretical bandwidths estrapolated from experimental data indicate that bandwidths as high as 5% are obtainable with ceramic radomes.

Available in PDF, EPUB and Kindle. Book excerpt: Solid State Materials have been gaining importance in recent times especially in the context of devices which can provide necessary infrastructure and flexibility for various human endeavours. In this context, microwave materials have a unique place especially in various device applications as well as in communication networks. Various technological developments are taking place in fine-tuning these materials for specific applicatio"ns and in fixed band frequencies. Though the science and technology of these materials has reached an advanced stage, systematic attempts are still lacking in bringing all available information in a single source. The present. volume is a modest attempt in this direction, though it cannot be considered to be the one that satisfies completely desired components and information required. The editors have enlisted certain articles of interest in this area, especially those dealing with measurement techniques, chapters dealing with materials like Ferrites, YIGs, Radome and high Tc superconducting materials which are of current interest. The editors are fully aware that the coverages are not comprehensive either in scope or in depth. The purpose of this volume is only to acquaint oneself of certain aspects of a fast developing field. The editors will be grateful for any comments or suggestions in this endeavour. V. R. K. MURTHY S. SUNDARAM B. VISWANATHAN Contents Preface v 1.

Available in PDF, EPUB and Kindle. Book excerpt: em style="mso-bidi-font-style: normal;"Radome Electromagnetic Theory and Design explores the theoretical tools and methods required to design radomes that are fully transparent to the electromagnetic energy transmitted or received by the enclosed antenna. A radome is a weatherproof and camouflaged enclosure that protects the enclosed radar or communication antenna, and are typically used on a fixed or moving platform such as an aircraft, ship or missile. The author — a noted expert in the field — examines the theoretical methods that apply to all type of radomes: planar, conformal, airborne and ground based. The text offers a description of the various measurement methods that characterise the electrical parameters of a radome, and discusses their merits in terms of accuracy. This groundbreaking book brings together in one volume all the necessary theoretical tools to design radomes

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to a range of jamming principles and techniques for new radars, combining a wealth of theoretical analyses, test data, calculations, and charts. With rapid advances in military radar technology, new types of radar are constantly emerging. Therefore, there is an urgent need to carry out effective research on these new radars and to develop corresponding jamming techniques. The main topics covered include development of radar and radar countermeasures; jamming techniques for synthetic aperture radar; jamming techniques for pulse compression radar; jamming techniques for pulse Doppler radar; general jamming techniques for various radars; analysis and calculation of the effective jamming suppression zone and jamming exposure zone for radars installed on different platforms; jamming techniques for phased array radar; jamming techniques for dual (multiple) static radar; and solutions for high equivalent radiation power, high reception sensitivity, and transceiver isolation in jammer design.
