An introduction to the most relevant theoretical and algorithmic
aspects of modern microwave imaging approaches

Microwave imaging--a technique used in sensing a given
scene by means of interrogating microwaves--has recently
proven its usefulness in providing excellent diagnostic
capabilities in several areas, including civil and industrial
engineering, nondestructive testing and evaluation, geophysical
prospecting, and biomedical engineering.

Microwave Imaging offers comprehensive descriptions of
the most important techniques so far proposed for short-range
microwave imaging--including reconstruction procedures and
imaging systems and apparatus--enabling the reader to use
microwaves for diagnostic purposes in a wide range of applications.
This hands-on resource features:

* A review of the electromagnetic inverse scattering problem
formulation, written from an engineering perspective and with
notations

* The most effective reconstruction techniques based on diffracted
waves, including time- and frequency-domain methods, as well as
deterministic and stochastic space-domain procedures

* Currently proposed imaging apparatus, aimed at fast and accurate
measurements of the scattered field data

* Insight on near field probes, microwave axial tomographs, and
microwave cameras and scanners

* A discussion of practical applications with detailed
descriptions and discussions of several specific examples (e.g.,
materials evaluation, crack detection, inspection of civil and
industrial structures, subsurface detection, and medical
applications)

* A look at emerging techniques and future trends

Microwave Imaging is a practical resource for engineers,
scientists, researchers, and professors in the fields of civil and
industrial engineering, nondestructive testing and evaluation,
geophysical prospecting, and biomedical engineering.
