JAKOB van ZYL, PhD, has been with the NASA Jet Propulsion
Laboratory since 1986. He has contributed to the design and
development of many SAR systems, including SIR-C, SRTM, AIRSAR,
TOPSAR, and GeoSAR. In 2010, he received the Distinguished
Achievement Award from the Geoscience and Remote Sensing Society of
the IEEE for his contributions to polarimatric SAR remote sensing.
Dr. Jakob van Zyl is the associate director of Project Formulation
and Strategy and NASA's Jet Propulsion Laboratory. Formerly, he was
the director for JPL's Astronomy and Physics Directorate.

YUNJIN KIM, PhD, has been with the NASA Jet Propulsion
Laboratory and¿California Institute of Technology since 1989.
He has contributed to the development of several radar systems,
such as SIR-C, AIRSAR, GeoSAR, and SRTM. Currently, Dr. Kim is the
Nuclear Spectroscopic Telescope Array (NuSTAR) project manager. He
is the author of two book chapters, more than twenty peer-reviewed
articles, and more than seventy conference publications.
