The book covers a variety of aspects central to radar remote sensing, with a focus on polarimetric topics. The chapters on electromagnetic wave propagation, antennas, radar and synthetic aperture radar, probability and random processes, and radar interferometry are introductory in nature. The book also provides the mathematical principles necessary to understand polarized wave transmission, propagation, and reception in communication systems and polarimetric-radar remote sensing. Problems ranging from introductory to challenging are provided throughout this pedagogical book.
