Description
Satellite-based Synthetic Aperture Radar (SAR) is a remote sensing
technique that has matured substantially over the past decade.
In the Earth Sciences, the use of repeat-pass interferometry
(InSAR) to study surface deformations associated with earthquakes
and volcanoes has received considerable attention. Yet, these
spectacular results have all been obtained using data from non-US
spacecraft, which were not optimized for this class of scientific
applications. For this reason, participants in the October 3-5,
1999 workshop on the Plate Boundary Observatory (PBO) formulated
a strong recommendation that NASA, NSF, USGS and other US agencies
should coordinate efforts to design, build, and launch a science-driven
SAR satellite mission. In their view, such a NASA-led multi-agency
mission would become an important component of the EarthScope
initiative.
The PBO Steering Committee has noted that
scientific applications of SAR extend well beyond the range covered
by EarthScope, especially if one includes the use of other radar
operation modes such as polarimetry or ScanSAR, including studies
of the cryosphere, hydrology, land-cover and vegetation, and
the open ocean. To date, there has not been a forum for these
diverse disciplines to exchange views and information, to explore
possible broad synergies, and to provide stewardship of a U.S.
radar program. This workshop will provide that opportunity. Its
Organizing Committee (3) invites participation of a wide spectrum
of Earth scientists, to define the science strategy for a national
scientific SAR mission. The workshop will produce a report describing
the scientific goals for such an initiative, the associated mission
requirements, and an implementation approach. It will describe
how a SAR mission would advance Earth science research, contribute
to education and outreach, benefit from other national initiatives
such as ITR, and complement the other components of the EarthScope
initiative.
The workshop will be limited to 120 participants.
Applicants are asked to provide a brief statement of interests,
specifying how they expect to contribute to the goals of the
workshop (using the form below).
Partial support (air travel, hotel, meals) will be provided from
workshop funds.

A New Earth Imaging Radar Mission
Synthetic Aperture
Radar Mission Study Report
This report reviews the history of the LightSAR project and summarizes
actions [NASA} can
undertake to support industry-led efforts to develop an operational
synthetic aperture radar (SAR)
capability in the United States. This is an interim report. After
appropriate consideration of
inputs from the science community and industry SAR users and
hardware providers, a final
report will be prepared.
Objectives
- To articulate a long-range scientific
and technological vision for SAR uses in the Earth Sciences
- To explore the diversity of scientific
applications of a US civilian SAR program, and to define the
specific science requirements for each of these applications
- To identify synergies between different
SAR applications, at the science and measurement requirements
level
- To identify scientific opportunities opened
by SAR imaging of Earth systems
- To articulate the role of SAR within the
EarthScope initiative
- To discuss strategies for a US science-driven
SAR observational program.
