Applied scientists and professionals need to appreciate the value of microwave remote sensing techniques - particularly now that a number of spaceborne systems (such as Envisat, Radarsat 2, Adeos and EOS) are being launched. This extensive introduction to microwave remote sensing, both active and passive, provides a solid primer for advanced, technically-oriented undergraduates and graduate students, and also provides an introduction to the subject for other remote sensing researchers and professionals unfamiliar with microwave remote sensing. It begins with a look at the physical principles and properties of microwaves, how they behave in the real world and are detected. It then gives a study of microwave systems: passive systems, basic principles of radar, conceptual issues of radar, and radar imaging and its applications; and moves on to the advanced topics of radar modelling, interferometry and polarimetry before concluding with an appendix giving some useful mathematics, notably trigonometry, logs and exponentials, complex numbers, vectors and matrices.
