  • Underwater Ranging and Localization

    This chapter focuses on two localization schemes that are developed and evaluated using OFDM modem prototypes. Both approaches are based on range measurements, and are applicable to a network with multiple nodes. The chapter presents the localization approach based on messages broadcast from multiple surface nodes, coupled with tracking algorithms and implemented on a physical system to provide a complete analysis. The advantage of the proposed localization method is that the broadcast messages can serve an arbitrary number of underwater nodes once they are in range, in contrast to many existing solutions which can only serve a small number of users. An on‐demand asynchronous localization (ODAL) scheme is presented. Several fixed‐position anchor nodes are deployed throughout the network and are assumed to have perfect knowledge of their own positions. These anchors need only know their own locations, and are not required to be surface nodes or have synchronized clocks.

  • Scattering by Turbulence, Particles, Diffuse Medium, and Rough Surfaces

    The scattering by turbulence is expressed by the scattering cross section per unit volume of turbulence, which is given by the correlation function or the spectrum of the fluctuation of dielectric constant or refractive index of the medium. Three commonly used spectra are Booker‐Gorden formula, Gaussian spectrum, and Kolmogorov spectrum. This chapter proposes a more realistic spectrum based on the actual turbulence characteristics. It discusses the scattering cross section per unit volume of turbulence. The scattering function of particles with size distributions can often be approximated by a Gaussian function. The Henyey‐Greenstein phase function is proposed to represent the optical diffuse scattering by small particles with size distribution. It has been shown to be useful for expressing optical scattering by fog and optical diffusion in tissues. The chapter describes two standard methods that deal with the scattering from rough surfaces. One is the "perturbation method" and the other is the "Kirchhoff approximation".

  • Coherence in Multiple Scattering and Diagram Method

    This chapter presents an introduction to "backscattering enhancement". It outlines the basic idea of enhanced backscattering in turbulence. Enhanced backscattering occurs in many areas of engineering including scattering from particles, rough surfaces, and turbulence. It is related to "retro reflectance" or "opposition" effects, and observed enhanced backscattering by soils and vegetation. Concerning the enhanced backscattering due to turbulence, a question may be asked about the relationship with power conservation. The conservation of power requires that the enhanced backscattered power needs to be balanced by the decrease of power. It is expected that the enhanced backscattering can occur, not only in turbulence, but for rough surfaces as well. The enhanced backscattering from rough surfaces is important in several applications, including the study of surface plasmon localization in rough‐metal surfaces, phonon localization, and ocean acoustic applications. Finally, the chapter presents simplified heuristic discussions of interesting coherent phenomena in multiple scattering.

  • Surface Waves Everywhere

    By ¿¿¿surface waves¿¿¿ one means a special kind of waves that propagate at the interface between two different media. These are certainly the first kind of surface waves that mankind has encountered. The wind can excite water waves with phase velocities that are inferior to the wind velocity. These are electromagnetic waves that exist when the dielectric constant is positive on one side of the interface and negative on the other side. Surface plasma waves can propagate along the interface between media with positive and negative dielectric constant. There exist two distinct situations: an ungated two¿¿¿dimensional electron gas (2DEG), in a quantum well or heterostructure, and a 2DEG with a metallic gate, like in a field¿¿¿effect transistors (FETs). In a crystal, the periodic structure of the lattice results in the band structure of the electron energy spectrum and the states are described by Bloch wavefunctions.

  • Stochastic Wave Theories

    This chapter presents a summary of the historical development of the statistical wave theories and new ideas, and key questions that may be outstanding or may need further attention. It also discusses the reciprocity relations for the radiative transfer. Radiative transfer has been applied extensively to geophysical remote sensing and scattering. Basic formulations of radiative transfer are closely related to neutron transport and Boltzmann's transport equation. It has been used in biomedical tissue optics, imaging, and ultrasound imaging of tissues. The Sommerfeld problem deals with radio waves over a flat earth. However, if people consider imaging of objects near the ocean surface or terrain, it may be necessary to study the effects of roughness of the surface. This is a study of "stochastic Green's function" for rough surfaces. This problem has been studied using Dyson and Bethe‐Salpeter equations for coherent and incoherent fields using the smoothed diagram method similar to Watson‐Keller studies.

  • OFDM in Deep Water Horizontal Communications

    This chapter focuses on two scenarios where the channel consists of long separately clusters, leading to an extremely large delay spread - on the order of seconds: deep‐water horizontal channel and underwater broadcasting networking. It is devoted to designing orthogonal frequency‐division multiplexing (OFDM) receiver processing algorithms to address both interblock interference (IBI) and possible ICI in the received signal. The chapter describes a decision‐feedback based equalizer and a factor‐graph based equalizer, respectively, for joint IBI and ICI equalization. It presents an iterative block‐to‐block receiver, where all the received blocks within one batch of transmission are decoded jointly.The chapter presentsdiscusses the performance results using both simulation and experimental data sets collected from the Atlantic Undersea Test and Evaluation Center (AUTEC) network. It demonstrates the application of the receiver developed for the deep water horizontal channel to an underwater broadcasting network, and shows emulated experimental results.

  • Femix Virtual Propagation Package

    This chapter discusses how the groundwave propagation problem over a non‐smooth spherical Earth with an impedance BC and a radially dependent atmosphere, excited by a vertical electric dipole located near the Earth's surface, requires the solution of a 3D EM wave equation in spherical coordinate. A novel FEMPE‐based software tool (FEMIX) is introduced for the analysis and visualization of surface‐wave propagation over the irregular Earth's surface through a homogeneous and an inhomogeneous atmosphere. The FEMIX propagator uses the FEM‐based standard PE, with the accuracy of the numerical computations depending on the discretization. Several parameters, such as the frequency, source beam‐ width, source tilt, source height, terrain profile, refractivity variations, need to be considered. The LOAD and SAVE buttons are used to load and record the irregular terrain data. New irregular terrain data are defined for each path on the bottom figure of the right part by using the number of points, range, and height values by pressing the Locate Points button.

  • VHF to SHF Radio Prediction

Particular attention is paid to the problems caused by Radio Controlled Improvised Explosive Devices (RCIEDs). **Key Features:** * * Written by an expert in both the civilian and military applications of the technology * Focuses on methods such as radio and radar jamming, and radio-controlled improvised explosive devices (IEDs) * Contains problems and solutions to clarify key topics

  • Planar Layers, Strip Lines, Patches, and Apertures

    This chapter discusses excitation of waves in planar layers and considers strip lines, patches, and apertures in dielectric layers which are useful in microwave and millimeter wave applications. The chapter also considers the excitation of transverse magnetic (TM) waves on a dielectric slab placed on a conducting plane, where it is the two‐dimensional problem. Strip lines have many attractive features. The most common types have a strip of conductor on a grounded dielectric slab. Even though the hybrid mode analysis is required for exact analysis of strip lines, simpler techniques can be used for approximate analysis of strip lines. One useful method is the quasi‐static approximation, in which Ez and Hz are neglected and the field is assumed to be transverse electro magnetic (TEM). Finally, the chapter examines periodically placed patches and apertures embedded in dielectric layers.

  • PE and Terrain Modeling

    This chapter explains how irregular terrain modeling can be implemented in the PE via several different mathematical approaches. The staircase approximation of the range dependent terrain profile is the best and easiest in order to handle DBC since neither analytical terrain function nor slope values are required. It emphasizes only on the requirement of the terrain height at each range step. Surface‐wave propagation along multi‐mixed propagation paths including irregular terrain profiles has long been a challenging wave propagation prediction problem. A highly attractive and effective model for the prediction of EM wave propagation effects above Earth's surface is the SSPE method. The PE model is a one‐way, forward propagation problem, which can be numerically discretized and solved via step‐by‐step iterative marching representations from source to receiver, using the finite‐difference, FEM, or MoM approaches as well as DFT algorithms.
