Book Synopsis Reduction of a Ship's Magnetic Field Signatures by : John Holmes
Download or read book Reduction of a Ship's Magnetic Field Signatures written by John Holmes and published by Morgan & Claypool Publishers. This book was released on 2008-10-08 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decreasing the magnetic field signature of a naval vessel will reduce its susceptibility to detonating naval influence mines and the probability of a submarine being detected by underwater barriers and maritime patrol aircraft. Both passive and active techniques for reducing the magnetic signatures produced by a vessel's ferromagnetism, roll-induced eddy currents, corrosion-related sources, and stray fields are presented. Mathematical models of simple hull shapes are used to predict the levels of signature reduction that might be achieved through the use of alternate construction materials. Also, the process of demagnetizing a steel-hulled ship is presented, along with the operation of shaft-grounding systems, paints, and alternate configurations for power distribution cables. In addition, active signature reduction technologies are described, such as degaussing and deamping, which attempt to cancel the fields surrounding a surface ship or submarine rather than eliminate its source. Table of Contents: Introduction / Passive Magnetic Silencing Techniques / Active Signature Compensation / Summary

Download or read book Exploitation of a Ship's Magnetic Field Signatures written by John J. Holmes and published by Morgan & Claypool Publishers. This book was released on 2006 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface ship and submarine magnetic field signatures have been exploited for over 80 years by naval influence mines, and both underwater and airborne surveillance systems. In this book, author John Holmes presents the generating mechanism of the four major shipboard sources of magnetic fields, along with a detailed description of the induced and permanent ferromagnetic signature characteristics.Holmes presents a brief historical summary of magnetic naval mine development during World War II followed by a discussion of important improvements found in modern weapons, including an explanation of the damage mechanism for non-contact explosions. This is followed by a brief historical discussion of underwater and airborne submarine surveillance systems and magnetic field sensing principles, in which mathematical formulations are presented for computing expected target signal strengths and noise levels for several barrier types.Also outlined is a multi-layered defensive strategy against naval mines, with graphical explanations of the relationships between ship signature reduction and minefield clearing effectiveness. Equations for estimating geomagnetic, ocean surface wave, platform, and vector sensor motion noises are presented along with simple algorithms for their reduction.

Book Synopsis Modeling a Ship’s Ferromagnetic Signatures by : John Holmes
Download or read book Modeling a Ship’s Ferromagnetic Signatures written by John Holmes and published by Springer Nature. This book was released on 2022-05-31 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferromagnetic models of ships and submarines that predict or reproduce their magnetic signatures have found applications in the development of both offensive and defensive military systems from World War II to the present. The mathematical basis of generalized coordinate systems will be presented and demonstrated with example applications to analytic spherical and prolate spheroidal magnetic ship models. In addition, the advantages and pitfalls of using complex finite-element- and boundary-element numerical techniques to predict high-order near-field ship signatures will be discussed, followed by a short description of the design and testing of complementary physical scale models. Extrapolation of measured magnetic signatures from testing environments to threat areas using semi-empirical math models will be presented, along with an explanation of their inherent instabilities and methods for regularizing them. These magnetic ship signature modeling techniques are used today in designing optimized signature reduction systems that have a minimum impact on ships and their systems. The discussion will be closed with an important discussion of the verification and validation of magnetic models of surface ships and submarines.

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.
