This course reviews the
theory and application of aerospace remote sensing imaging radar methods to
earth science studies. Imaging radars offer earth scientists a unique and
powerful set of methods to study the surface characteristics and topographic
form of the crust and oceans, including ice and vegetation cover, over large regions at
high spatial resolution. Over the past 30 years, remote sensing imaging radar
methods have benefited from numerous conceptual and technological advances that
have led to the development of the revolutionary satellite Differential
Interferometric Synthetic Aperture (DInSAR) method. Just one of several
imaging radar methods studied in the course, DInSAR is producing important
economic and scientific results through monitoring sub-centimeter level crustal
deformation related to earthquakes, volcanic intrusion, landslides, groundwater
and petroleum production. The course affords students the opportunity and
computing resources to apply advanced radar imaging methods, including DInSAR,
in their term projects. Contact Dr. Oppliger for more information.

COURSE DESCRIPTION
This course reviews fundamental
principles of aerospace remote sensing in the microwave portions of the
electromagnetic spectrum. Students learn how the energy-path concept provides a
model for understanding the properties of the sources of microwave
electromagnetic radiation and the transmitting media. Concepts of frequency,
wavelength and phase are learned and the properties of microwave energy are
understood by students. Students learn the phenomenology of atmospheric effects
to develop an understanding of the impact of atmospheric scattering, absorption,
polarization, and ionospheric and tropospheric decorrelation on microwave energy
propagated to and received from the Earth’s surface.
Students learn radar system
parameters including: Earth curvature, orbit characteristics, the Radar
Equation, definitions, radar operation, phase noise, polarization, radar
resolution, illumination geometry and landscape geometry, image geometry and
inherent distortions, and speckle in radar imagery. Environmental and target
parameters learned include: concepts of roughness, geometry of targets,
resonance, dielectric constant, surface and volume scattering, signal
penetration and signal enhancement. Interpretation techniques, procedures and
aids are reviewed, including: interpretation keys, merged radar sets,
multifrequency-multipolarization radar analysis, filters and enhancements,
manual versus computer assisted interpretation.
Students learn basic
radargrammetry including: basic radargrammetry equations, projection equations,
relief displacement, matching radar images and digital terrain models, geometric
rectification, stereoscopic radar analysis, and parallax radargrammetry.
Students learn concepts and applications of radar polarimetry including:
polarimetry in nature, basic equations of radar polarimetry, antenna concepts,
target concepts, optimum polarization for maximum power, co-polarization and
cross-polarization, and geoscience applications of radar polarimetry.
Students learn concepts of imaging
radar interferometry including: overview of interferometry principles,
interferometric topographic mapping, velocity mapping, change mapping and
geoscience applications, including earthquake hazard and event analysis,
volcanic hazard detection, glacier and ice movement, landslide and erosion
detection, etc. Students construct radar interferograms using the SUN – Solaris
8 radar image processing workstation with JPL ROI_PAC software in the Arthur
Brant Laboratory for Exploration Geophysics.
Students study the physics of
surface scattering, reflection, of microwave EMR by major classes of earth
surface materials, with emphasis on the physical and electrical properties of
minerals and consolidated rocks, unconsolidated rock-weathering products, soils,
and coatings and alteration products that occur with these materials.
Sensor technology is reviewed in
terms of microwave physics and antenna technology. Students gain an
understanding of the models used to characterize radar backscatter to understand
how microwave EMR, measured by airborne and spaceborne radar antennas, is
formatted to data. Concepts of radiometric and geometric adjustments to
microwave data are applied by students. Spaceborne radar systems are reviewed
including: SEASAT-A, SIR-A, SIR-B and SIR-C/X-SAR, Kosmos, Almaz, ERS-1 and
ERS-2, J-ERS-1, and RADARSAT. Aircraft radar systems are reviewed including:
AirSAR, C/X SAR, E-SAR and STAR-1.
Students learn how to conduct
ground-based field and laboratory studies of common rock materials and their
associated rock alteration products to develop an appreciation of the microwave
attributes of natural resource types measured with aerospace remote sensing
techniques. Microwave data analysis techniques are introduced over known
geology in the Great Basin. The cost-effectiveness of radar imagery is compared
to optical imagery and thermal imagery for natural resources investigations..

COURSE NOTEBOOK
This course has no course textbook, however
students are expected to develop their own course textbook through lecture notes
taken in class, notes taken from assigned readings and notes taken from
reference materials that students wish to include on their own initiative.
Please do not just copy references from this course for your notebook!
Your interpretations of the key points in these references are what should
constitute most of your notebook. An important part of the notebook is a
comprehensive list of references, appropriate to each major subject, and
including references you may find beyond those assigned during class. The
notebook will be professionally prepared, including carefully illustrated
diagrams. It will be appropriately footnoted to acknowledge sources of
information, and it will be organized in a three-ring binder. These notebooks
will be graded for completeness and neatness. Notebooks submitted by students
may be retained by the instructor and the information contained in the notebooks
will not be subject to copyright by the student. The instructor reserves the
right to use materials from the submitted notebooks for future classes. Some of
the material in the submitted course notebooks may be placed, in condensed form,
on the World Wide Web for the use of all students.
TERM PROJECT
The term project will involve student
laboratory research on characterizing geoscience problems in terms of the kinds
of microwave attributes that can be detected and mapped with aerospace remote
sensing data. Students in the class are encouraged work as a team to acquire
radar image data, over a geological problem area for analysis with ENVI, ER-Mapper
and/or JPL ROI-PAC software. Term projects must be approved by the instructor
and should be arranged during the first week or two of instruction.
We have developed a technique for documenting
the steps students might utilize in computer analysis of remote sensing data in
their term projects. This documentation takes the form of saving the computer
screen showing the procedures used. This type of documentation should be
utilized in an appendix at the end of the report. Powerpoint illustrations and
image data acquired and processed in the course of the term project should be
provided to the instructor in the form of a CD-ROM, or 100 MB ZIP Disk as
appropriate. Large data sets may have to be archived on our Peerless 20GB
removable drives. Students are encouraged to consider publishing their term
reports after suitable peer review. The instructor will be pleased to assist in
any publication effort.
The methodology for term projects will take the
form of (1) definition of a project, (2) identification of suitable data and
development of a general outline to be submitted to the instructor for his
review, (3) expansion of the project outline, with key references noted, after
project work is underway (graded), (4) preliminary results and findings
submitting as a topic sentence outline for the proposed project report. The
topic sentence outline and bibliography will be evaluated for completeness and
they will be graded. The final report is due typewritten, in professional style
on the last day of the course. Late reports will be downgraded accordingly.
Incompletes are strongly discouraged and must be adjudicated with the
instructor.
ORAL REPORT
The oral report will be a professionally
prepared talk that uses “MS Powerpoint” for original figures and diagrams.
Figures and diagrams from reference sources must be carefully documented. The
oral report will be presented as a 20 minute presentation with 5 minutes for
questions and answers, in a manner similar to that in a professional association
meeting. The class will participate in the evaluation of the presentation, in
terms of its organization, style and content. These talks are designed to
improve student communication skills and to prepare students for professional
life. The oral reports will be given at the end of the course and students may
invite guests to attend.
