Principles of Synthetic Aperture Radar Imaging: A System Simulation Approach demonstrates the use of image simulation for SAR. It covers the various applications of SAR (including feature extraction, target classification, and change detection), provides a complete understanding of SAR principles, and illustrates the complete chain of a SAR operation. The book places special emphasis on a ground-based SAR, but also explains space and air-borne systems. It contains chapters on signal speckle, radar-signal models, sensor-trajectory models, SAR-image focusing, platform-motion compensation, and microwave-scattering from random media. While discussing SAR image focusing and motion compensation, it presents processing algorithms and applications that feature extraction, target classification, and change detection. It also provides samples of simulation on various scenarios, and includes simulation flowcharts and results that are detailed throughout the book. Introducing SAR imaging from a systems point of view, the author: Considers the recent development of MIMO SAR technology Includes selected GPU implementation Provides a numerical analysis of system parameters (including platforms, sensor, and image focusing, and their influence) Explores wave-target interactions, signal transmission and reception, image formation, motion compensation Covers all platform motion compensation and error analysis, and their impact on final image radiometric and geometric quality Describes a ground-based SFMCW system Principles of Synthetic Aperture Radar Imaging: A System Simulation Approach is dedicated to the use, study, and development of SAR systems. The book focuses on image formation or focusing, treats platform motion and image focusing, and is suitable for students, radar engineers, and microwave remote sensing researchers.

Remote Sensing of Hydrometeorological Hazards

Author: George P. Petropoulos
Publisher: CRC Press
ISBN: 9781351650977
Release Date: 2017-11-02
Genre: Mathematics

Extreme weather and climate change aggravate the frequency and magnitude of disasters. Facing atypical and more severe events, existing early warning and response systems become inadequate both in scale and scope. Earth Observation (EO) provides today information at global, regional and even basin scales related to agrometeorological hazards. This book will focus on drought, flood, frost, landslides, and storms/cyclones and will cover different applications of EO data used from prediction to mapping damages for each category. It will explain the added value of EO technology in comparison with conventional techniques applied today through many case studies.

Microwave Remote Sensing of Sea Ice

Author: Frank D. Carsey
Publisher: American Geophysical Union
ISBN: 9780875900339
Release Date: 1992-04-08
Genre: Science

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 68. Human activities in the polar regions have undergone incredible changes in this century. Among these changes is the revolution that satellites have brought about in obtaining information concerning polar geophysical processes. Satellites have flown for about three decades, and the polar regions have been the subject of their routine surveillance for more than half that time. Our observations of polar regions have evolved from happenstance ship sightings and isolated harbor icing records to routine global records obtained by those satellites. Thanks to such abundant data, we now know a great deal about the ice-covered seas, which constitute about 10% of the Earth's surface. This explosion of information about sea ice has fascinated scientists for some 20 years. We are now at a point of transition in sea ice studies; we are concerned less about ice itself and more about its role in the climate system. This change in emphasis has been the prime stimulus for this book.

Advances in SAR Remote Sensing of Oceans

Release Date: 2018-10-12
Genre: Technology & Engineering

SAR remote sensing for ocean and coast monitoring has become a very popular area of geoscience and remote sensing research in recent years. This book is focused on ocean dynamical studies of sea surface phenomena, air-sea interactions, anthropogenic object detection and radar imaging mechanisms. The objective is to demonstrate the types of information that may be obtained from SAR images of the ocean, and the cutting-edge methods of analyzing the imagery. It is intended for scientific researchers as well as graduate and/or senior undergraduate students who wish to use remotely sensed radar data in oceanographic research.

Formales SQL Tuning f r Oracle Datenbanken

Author: Leonid Nossov
Publisher: Springer-Verlag
ISBN: 9783662452929
Release Date: 2016-02-05
Genre: Computers

Das Ziel des SQL-Tunings ist eine Verbesserung des bestehenden Ausführungsplans. Die in diesem Buch beschriebene Methode kann man „Bremsenbeseitigung im Ausführungsplan“ nennen. Solche „Bremsen“ oder Engpässe lassen sich durch eine formale Analyse des Ausführungsplans erkennen. Dafür sind keine Datenmodellkentnisse notwendig. Das ist besonders vorteilhaft für Datenbankadministratoren, weil sie in der Regel gar nicht oder unzureichend gut mit dem Datenmodell vertraut sind. Im Buch werden zahlreiche praktische Erfahrungen mit dieser Methode präsentiert.

Photogrammetrie

Publisher: Walter de Gruyter
ISBN: 9783110908039
Release Date: 2004-01-01
Genre: Science

Volume1 of this three volume series of textbooks on photogrammetry is dedicated to the fundamentals and standard procedures, both for photogrammetry and for laser scanning that have come to the fore in recent years. Using photogrammetry and laser scanning, it is mainly the position and form of objects that are recorded and modelled. Data capture sensors are fitted to aircraft, and to terrestrial platforms for work in the immediate vicinity. Results from modelling are partly visualized as vector graphics and partly as bit-maps.

Microwave Propagation and Remote Sensing

Author: Pranab Kumar Karmakar
Publisher: CRC Press
ISBN: 9781351833318
Release Date: 2017-12-21
Genre: Science

Because prevailing atmospheric/troposcopic conditions greatly influence radio wave propagation above 10 GHz, the unguided propagation of microwaves in the neutral atmosphere can directly impact many vital applications in science and engineering. These include transmission of intelligence, and radar and radiometric applications used to probe the atmosphere, among others. Where most books address either one or the other, Microwave Propagation and Remote Sensing: Atmospheric Influences with Models and Applications melds coverage of these two subjects to help readers develop solutions to the problems they present. This reference offers a brief, elementary account of microwave propagation through the atmosphere and discusses radiometric applications in the microwave band used to characterize and model atmospheric constituents, which is also known as remote sensing. Summarizing the latest research results in the field, as well as radiometric models and measurement methods, this book covers topics including: Free space propagation Reflection, interference, polarization, and other key aspects of electromagnetic wave propagation Radio refraction and its effects on propagation delay Methodology of estimating water vapor attenuation using radiosonde data Knowledge of rain structures and use of climatological patterns to estimate/measure attenuation of rain, snow, fog, and other prevalent atmospheric particles and human-made substances Dual/multifrequency methodology to deal with the influence of clouds on radiometric attenuation Deployment of microwaves to ascertain various tropospheric conditions Composition and characteristics of the troposphere, to help readers fully understand microwave propagation Derived parameters of water, free space propagation, and conditions and variable constituents such as water vapor and vapor pressure, density, and ray bending
