Theory and practice of GNSS reflectometry This is the first authored English book completely focused on global navigation satellite system reflectometry (GNSS R). It consists of two main parts: the fundamental theory; and major applications which include ocean altimetry sea surface wind speed retrieval snow depth measurement soil moisture measurement tsunami detection and sea ice detection. Striking a healthy balance between theory and practice and featuring in depth studies and extensive experimental results the book introduces beginners to the fundamentals while preparing experienced researchers to pursue advanced investigations and applications in GNSS R
