We would like to thank Professor Emeritus Wolfgang-Martin Boerner for writing the foreword of this book. His devoted involvement in polarimetric radar development, and his encouragement to fellow researchers, ‘‘polarimetry co-strugglers,’’ led to many advancements over the last 20 years and ultimately made this book a reality. We also would like to acknowledge Dr. Thomas Ainsworth, Naval Research Laboratory, and Professor Boerner for reading the chapters and providing valuable suggestions and Dr. Hab Laurent Ferro-Famil, University of Rennes-1, for his contribution to Chapter 9. We are most grateful for their help
