Book Description
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

Book Description
Sea Clutter: Scattering, the K Distribution and Radar Performance examines the statistics of radar scattering from the sea surface in terms of their relevance to radar operating in a maritime environment; including remote sensing, surveillance and targeting applications. A lot of the work in the book is based on the compound Kdistribution model for the amplitude statistics of sea clutter. In addition, the book addresses the specification of performance required by customers and the measurement of performance of systems supplied to customers.

Book Description
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.

Book Description
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 Description
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.
