This introduction to the use of radar for the remote sensing of natural surfaces providesd the reader with a thorough grouniing in practical applications, focusing particularly on terrestrial studies that may be extneded to other palnets.
An historical overview of the subject is followed by three chapters that introduce the nomenclature and methodology pertaining to radar data collection, image interpretation, surface roughness analysis, and dielectric constant measurements. The author then presents a summary of theoretical explanations for the backscatter properties of continuous rough surfaces, collections of discrete objects, and layered terrain. The uses and limitations of common scattering models are reviewed, and in many cases empirical relationships between surface properties and radar echoes are presented as a guide to further theoretical studies. These are illustrated with examples from the natural environment such as lava flows, rock-strewn surfaces, and sand dunes. The final two chapters review radar surveys of the Moon, Mercury, Venus, and Mars and dempnstrate how radar techniques may be used to further our understanding of these remote bodies.
The subject matter is presented at a level apporpriate for students across a broad range of scientific disciplines, although particular emphasis is given to practical geological and geophyhsical studies of the Earth and palnets. This book is therefore suitable for advanced undergraduates, Graduate students, and professionals in the Earth and planetary sciences, electrical engineering, and remote sensing.
