목차/설명	Oringally published in 1975, Radar Reflectivity of Land and Sea has been revised and updated with a foreword containing an extensive bibliography, and appendices. The new material includes discussions on temporal and spatial statistics of radar echo, comparisons between lognormal and Weibull distribution, and dependencies of tree echo spectra on wavelength. This revised edition provides references to land and sea clutter models and sources of new data for microwaves and millimeter waves. Focusing on microwave backscatter, the book will be of prime interest to radar engineers and those who use radars to solve problems in target detection and early warning, navigation, mapping and surveillance, and measurement of surface properties. In reference to the first edition of Radar Reflectivity of Land and Sea, David K. Barton said: “A thorough discussion of radar backscattering phenomenon from land and sea surfaces, including both theory and experimental data...a useful teaching text for specialized courses, as well as a reference for radar system designers...” Contents: Remote Sensing by Radar. Basic Concepts and Definitions. Polarization, Depolarization, and Theories of Scattering. Effects of the Earths Surface. Echo Fluctuations. Average and Median Cross Sections. Interdependence of Polarization Characteristics. Appendices. New radar engineers will find this to be a valuable, all-encompassing, well-illustrated survey of radar reflectivity fundamentals. Veteran engineers and systems designers will appreciate the book뭩 new coverage of: effects of frequency agility, spatial averages for terrain, graphs from GIT clutter models, land and sea echo at extremely low grazing angles, compound statistics including the K and the Rayleigh modulated by Wiebull distributions, super sea echo events and sea spikes, bistatic land and sea clutter, and more.
