1. SCOPE 1.1 Scope. This document specifies standard practices to facilitate achievement of the intra-ship and inter-ship electromagnetic compatibility (EMC), electromagnetic pulse (EMP), bonding, and intermodulation interference (IMI) requirements of MIL-STD-464. 1.2 Application. The requirements specified herein apply to metal and nonmetallic hull ships and are applicable during ship construction, overhaul, alteration, and repair. Requirements herein may be invoked upon contractor and government (military and civilian) personnel. 1.3 Tailoring. The requirements herein may be tailored with NAVSEA 05H3, Navy technical warrant authority, approval. 1.4 New materials and technology. To achieve requirements of this standard while reducing lifecycle maintenance costs, implementation of new materials and technology is encouraged. The new materials and technology should not prevent the ship from meeting all applicable MIL-STD-464 E3 performance requirements, and must not introduce EMI or safety problems.

Modern combat ships are crucially dependent on electromagnetic systems including numerous and varied types of antennas. There are many shipboard communication antenna parameters such as location, number, type, and survivability of given antenna systems. Each of these parameters can be varied to determine the overall optimal system. This thesis investigates computer numerical models to improve combat survivability of HF shipboard antenna systems. Future generations of ships will have low profile combat survivable antennas. Possible improvements for present ships might be the elimination of fragile HF antennas by exciting existing mast structures. Two mast configurations resembling an FFG-45 class ship are investigated for various heights: (1) a simplified rectangular column representing a forward mast. The masts are modeled by using surface patches and wire grids. Six computer models of the given masts are developed by the Numerical Electromagnetics Code (NEC).

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. The generating mechanism of the four major shipboard sources of magnetic fields is explained, along with a detailed description of the induced and permanent ferromagnetic signature characteristics. A brief historical summary of magnetic naval mine development during World War II is followed by a discussion of important improvements found in modern weapons, including an explanation of the damage mechanism for non-contact explosions. A strategy for selecting an optimum mine actuation threshold is given. A multi-layered defensive strategy against naval mines is outlined, with graphical explanations of the relationships between ship signature reduction and minefield clearing effectiveness. In addition to a brief historical discussion of underwater and airborne submarine surveillance systems and magnetic field sensing principles, mathematical formulations are presented for computing the expected target signal strengths and noise levels for several barrier types. Besides the sensor self-noise, equations for estimating geomagnetic, ocean surface wave, platform, and vector sensor motion noises will be given along with simple algorithms for their reduction.

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.

GROUNDS FOR GROUNDING Gain a comprehensive understanding of all aspects of grounding theory and application in this new, expanded edition Grounding design and installation are crucial to ensure the safety and performance of any electrical or electronic system irrespective of size. Successful grounding design requires a thorough familiarity with theory combined with practical experience with real-world systems. Rarely taught in schools due to its complexity, identifying and implementing the appropriate solution to grounding problems is nevertheless a vital skill in the industrial world for any electrical engineer. In Grounds for Grounding, readers will discover a complete and thorough approach to the topic that blends theory and practice to demonstrate that a few rules apply to many applications. The book provides basic concepts of Electromagnetic Compatibility (EMC) that act as the foundation for understanding grounding theory and its applications. Each avenue of grounding is covered in its own chapter, topics from safety aspects in facilities, lightning, and NEMP to printed circuit board, cable shields, and enclosure grounding, and more. Grounds for Grounding readers will also find: Revised and updated information presented in every chapter New chapters on grounding for generators, uninterruptible power sources (UPSs) New appendices including a grounding design checklist, grounding documentation content, and grounding verification procedures Grounds for Grounding is a useful reference for engineers in circuit design, equipment, and systems, as well as power engineers, platform, and facility designers.
