This introduction to the use of radar for remote sensing of natural surfaces provides the reader with a thorough grounding in practical applications, focusing particularly on terrestrial studies that may be extended to other planets. An historical overview of the subject is followed by an introduction to the nomenclature and methodology pertaining to radar data collection, image interpretation and surface roughness analysis. The author presents a summary (illustrated with examples from the natural environment) of theoretical explanations for the backscatter properties of continuous rough surfaces, collections of discrete objects, and layered terrain.
This 2002 introduction to the use of radar for remote sensing of
natural surfaces provides the reader with a thorough grounding in
practical applications, focusing particularly on terrestrial
studies that may be extended to other planets. An historical
overview of the subject is followed by an introduction to the
nomenclature and methodology pertaining to radar data collection,
image interpretation and surface roughness analysis. The author
then presents a summary (illustrated with black and white examples
from the natural environment) of theoretical explanations for the
backscatter properties of continuous rough surfaces, collections of
discrete objects, and layered terrain. Case studies of radar
surveys of the Moon, Mercury, Venus and Mars complete the book. The
level is appropriate for students and professionals across a broad
range of scientific disciplines including Earth and planetary
sciences, electrical engineering, and remote sensing. Particular
emphasis is given to practical geological and geophysical studies
of the terrestrial planets.
To have a voice in shaping government policy has been a goal of the
American people since the nation's founding. Yet, government seems
even less accessible now than in the past. An increasing rate of
incumbency in Congress, the unwieldy committee system that controls
legislation, and the decline of political parties have all weakened
representation and alienated Americans from the seat of power. The
one remaining way to produce major and coherent change in national
policy is through partisan realignment-a sharp, enduring shift in
voter support of the two major parties. This book is about the
phenomenon of realignment in American politics. It not only brings
together and assesses previous work in the area but also breaks new
ground in the analysis of the effects of realignment on political
elites and public policy. In addition, it is the first study to
present an integrated theory of realignment that can be applied to
the understanding of mass, elite, and policy change in times of
social crisis. Contributors include Lawrence McMichael, David
Nexon, Louis Seagull, Robert Lehnen, Philip Converse, Gregory
Markus, Lester Seligman, Michael King, David Brady, Kenneth Meier,
Kenneth Kramer, David Adamany, Charles Stewart, Susan Hansen, and
the editors.Bruce A. Campbell taught political science at the
University of Georgia. He is the author of The American Electorate.
