This book is a valuable reference book on weather radars and their associated algorithms, and it is written by a vital member of the University of Oklahoma Advanced Radar Research Center. As someone who originally studied physics for his B.S. degree and then, apparently, became an enthusiast of the physical interactions occurring around hydrometeorological targets, the author has poured all of the necessary physical explanations, relevant equations, and measurement techniques involving modern polarimetric weather radar into this book. The work is impressively organized in the ascending complexity of the topics it covers. An engineer or scientist who is new to the subject will find it very easy to read, since it covers almost all of the necessary preliminary information in a highly descriptive manner—amazingly, without forcing the reader to check many of the previous references.
