Book excerpt: Radar Propagation and Scattering in a Complex Maritime Environment addresses advanced numerical techniques used to significantly reduce the complexity and memory requirement for solving the linear system that results from the discretization of the boundary integral equations by the Method of Moments (MoM). Typically, the problem of the VHF wave scattering from an object above a rough sea surface in a ducting environment is investigated as is the HF radar propagation above the Earth in the presence of islands. Along with these topics, the book also covers rapid asymptotic theories, which are derived and compared with references methods based on the MoM. Presents tactics on scattering from both rough surfaces and near a rough surface Discusses radar propagation in ducting environments Includes numerical techniques to accelerate MoM

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation evaluates multiple effects that will cause a satellite borne radar to observe transformation of the transmitted polarization by an ocean surface. Knowing the surface conditions over large swaths of ocean is very important for both global weather prediction and for safety of navigation at sea. Fully polarimetric linearly polarized ocean observation radars use the linear cross-polarized ocean response to obtain an assessment of the surface wind vectors. However, radar technology is evolving. More compact hybrid polarization radars that transmit a single circular polarization, and then simultaneously receive two orthogonal linear polarizations are expected to obtain near fully polarimetric capability with a significant savings in weight, volume, and complexity. The models used by fully polarimetric linearly polarized radars to obtain the surface wind vectors are empirical, and not usable for hybrid compact polarimetric radars. The literature survey indicated two areas needed investigation to develop ocean observation capabilities for hybrid compact polarimetric radar. The first is for antenna cross-polarization isolation models specific to hybrid polarization radars. The second is for improved understanding of the nature of the ocean's polarimetric response to hybrid polarizations. Conclusions include that hybrid polarizations provide opportunities to polarimetrically isolate surface features, including surface roughness, the surface specular response, and breaking waves. These features should provide insight into surface winds, wave steepness, and sea state.

This book was released on 1983 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The propagation-loss, noise and scattering mechanisms involved in ground-wave radar for sea-state sensing and ship-tracking are first reviewed, taking as an example a coastal installation in the U.K. Techniques for extracting surface-current, surface-wind and directional sea-wave spectrum from first and second-order sea-echo are described, with reference to the influence of the antenna directivity and propagation factors. The special factors affecting ship-tracking in range, azimuth and Doppler are illustrated. The second part of the review concerns the use of sky-wave radar for sea-state sensing and for assessing the ionospheric layer configuration and propagation mode patterns. Sea-state sensing is shown to require real-time propagation assessment for effective frequency-management. Rapid sweep-frequency, sweep-azimuth and Doppler analysis are shown to be desirable.

Book excerpt: Reeds Introductions: Physics Wave Concepts for Marine Engineering Applications covers the fundamental theoretical maritime physics concepts which underpin electromagnetic wave and sonar principles as developed in most maritime-related courses, whether Naval, Coastguard or Merchant Marine engineering. For these reasons it is vital that maritime users have a basic understanding of the concepts upon which many essential modern sea-going sensors and communications devices now operate. Knowledge regarding electromagnetic waves and electromagnetic devices is an established merchant navy sea service requirement, particularly for the Standards in Training and Certification in Watchkeeping (STCW95) qualification in various Maritime Coastguard Agency exams, e.g. Marine Electrotechnology (as Chief Engineer and Second Engineer), as mandated by the UK Department for Transport. This short introductory book is written as simply as possible to support growing numbers of overseas students for whom English is not their first language. This volume provides a comprehensive study of maritime physics principles and provides a firm foundation prior to reading and studying of the following Reeds Marine Engineering series: Vols 1, 3, 6, 7, 14 and 15. Students having read this easy-to-read volume will be better prepared for the more in depth study of the other volumes listed.

This book was released on 2012-12-06 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago, de Loor and co-workers at TNO, The Netherlands, were the first to report bottom topography patterns in real aperture radar (RAR) images of the southern North Sea. At that time, this was a real puzzle. The skin depth of microwaves for sea water is only of the order of centimeters while the sea bottom is about 20 meters below the surface. Electromagnetic radiation therefore cannot probe the bottom directly. Similar phenomena were found in radar imagery from SEASAT and SIR-AlB synthetic aperture radars (SAR's) of Nantucket Shoals, the English Channel and many other coastal areas. Since then theory and ocean field experiments (Le., Phelps Bank, Georgia Straits, SARSEX, TOWARD, FASINEX, etc.) have advanced our understanding considerably. We now know that these surface signatures are the results of surface currents, perturbed by the bottom topography, which refract the propagation and modulate the energy of (short) surface waves so as to cause microwave backscatter power variations. Hence, any large scale ocean features containing nonuniform surface currents (i.e. internal waves, eddies, fronts, etc.) will cause similar manifestations in the radar imagery by means of current-wave-microwave interactions. Observations confirm this.

Book excerpt: Nonlinear Ocean Dynamics: Synthetic Aperture Radar delivers the critical tools needed to understand the latest technology surrounding the radar imaging of nonlinear waves, particularly microwave radar, as a main source to understand, analyze and apply concepts in the field of ocean dynamic surface. Filling the gap between modern physics quantum theory and applications of radar imaging of ocean dynamic surface, this reference is packed with technical details associated with the potentiality of synthetic aperture radar (SAR). The book also includes key methods needed to extract the value-added information necessary, such as wave spectra energy, current pattern velocity, internal waves, and more. This book also reveals novel speculation of a shallow coastal front: named as Quantized Marghany's Front. Rounding out with practical simulations of 4-D wave-current interaction patterns using using radar images, the book brings an effective new source of technology and applications for today’s coastal scientists and engineers. Solves specific problems surrounding the nonlinearity of ocean surface dynamics in synthetic aperture radar data Helps develop new algorithms for retrieving ocean wave spectra and ocean current movements from synthetic aperture radar Includes over 100 equations that illustrate how to follow examples in the book

This book was released on 1987 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some properties of the vector integral equation representing a general formulation for propagation and scattering from rough surfaces are discussed. It is shown that under certain conditions the equation may be reduced to a Volterra equation of the second kind in the normal component of the surface field for an initially unexcited surface, and hence some confidence may be had in a Neumann series or successive approximation solution. Using the formulation, the backscattered field solutions at ground wave frequencies and resulting radar cross section solutions derived previously for a model of the ocean surface are presented and discussed. The source assumed is a vertical pulsed dipole. The choice of receiving antenna is left arbitrary. the second order cross section contains new terms in addition to those provided by existing theories. The additional terms may become very significant in certain Doppler frequency regions and hence required for ocean clutter estimation in the detection of certain types of surface targets. Some of the new predictions have been verified experimentally.
