Dr. Romeiser has wide experience in the remote sensing of
winds, waves, and current fields by various microwave sensors
– altimeter, scatterometer, conventional and interferometric
synthetic aperture radar (SAR / InSAR). He has been involved
in many theoretical studies and experiments, and he has
developed the numerical SAR / InSAR imaging model “M4S“.
Furthermore, Dr. Romeiser is an Associate Editor of the IEEE
Journal of Oceanic Engineering. His current research interests
focus on the theoretical modeling and interpretation of SAR
and InSAR signatures of ocean features associated with
spatially varying surface currents and winds, the development
of quantitative geophysical parameter retrieval algorithms,
and performance studies for future spaceborne SAR / InSAR
