# Polarimetric Radar Imaging: From Basics to Applications Polarimetric radar imaging is a technique that uses the polarization properties of electromagnetic waves to enhance the information content of radar images. This book provides a comprehensive overview of the fundamentals of polarimetric radar imaging, along with its applications in various fields such as remote sensing, environmental monitoring, and disaster management. The book is structured into ten chapters, each covering different aspects of polarimetric radar imaging, including the principles of electromagnetic wave polarization, scattering models, speckle statistics, and image processing techniques. The first chapter introduces the history and development of polarimetric radar imaging, highlighting its evolution from basic radar systems to advanced polarimetric systems. It also discusses the basic concepts of SAR (Synthetic Aperture Radar) image formation and the different types of polarimetric SAR systems used in airborne and spaceborne applications. The second chapter covers the electromagnetic vector wave and polarization descriptors, including the Jones vector and Stokes vector, which are essential for describing the polarization state of electromagnetic waves. The third chapter discusses the electromagnetic vector scattering operators, including the scattering matrix and the polarimetric coherency and covariance matrices, which are used to model the scattering behavior of targets. The fourth chapter focuses on the statistical properties of polarimetric SAR speckle, including the Rayleigh speckle model, the K-distribution, and the effects of speckle spatial correlation on image quality. The fifth chapter presents various speckle filtering techniques for polarimetric SAR data, including the refined Lee filter and scattering model-based filters. The sixth chapter introduces the concept of polarimetric target decomposition, which is used to analyze the scattering properties of targets in polarimetric SAR images. The seventh chapter discusses the H/A/α polarimetric decomposition theorem, which provides a framework for classifying and analyzing the scattering properties of targets based on their polarization characteristics. The eighth chapter presents the application of polarimetric SAR in terrain and land-use classification, using statistical methods such as the maximum likelihood classifier and the complex Wishart classifier. The ninth chapter discusses the use of polarimetric interferometry (Pol-InSAR) for forest mapping and classification, highlighting the advantages of this technique in detecting forest structures and estimating forest height. The tenth chapter covers various applications of polarimetric SAR, including the analysis of man-made structures, the estimation of polarization orientation angles, the remote sensing of ocean surfaces, and the estimation of ionospheric Faraday rotation. The book also discusses the analysis of nonstationary natural media using a 2-D time-frequency approach, which is useful for detecting changes in the polarization properties of natural media over time. The authors, Jong-Sen Lee and Eric Pottier, are both experts in the field of polarimetric radar imaging and have contributed significantly to the development of polarimetric SAR technology. The book is a valuable resource for researchers, engineers, and students interested in the field of radar# Polarimetric Radar Imaging: From Basics to Applications Polarimetric radar imaging is a technique that uses the polarization properties of electromagnetic waves to enhance the information content of radar images.
