This book is a monograph on the reflection or scattering of electromagnetic waves, particularly radio waves, from rough surfaces such as irregular terrain, rough layers in the troposphere, the rough surface of the sea, the rough surfaces of the moon and planets, etc. It is intended for scientists working in the fileds of radio wave propagation and electromagnetic theory, bu the theoretical part of the book may be equally useful for acousticians. It assumes a knowledge of mathematics and electromagnetic theory at the graduate level (Physics or Electrical Engineering), though the reader can be a newcomer without background in this particular subject, as the problem is treated from first principles and particular mathematical tools (e.g. Bessel Functions and the theory of random variables) are summarized in the appendix.
The book is divided into two parts. Part 1, "Theory" gives the general principles of the theory, in particular the solutions for periodic and random roughness. Part 2, "Application" applies this theory to the propagation of radio waves in irregular terrain over the rough surfaces of the sea, to tropospheric scateer propagation and to radar reflections from the moon.
