Dr. Othmar Frey

Senior project scientist

 

The main experience of Othmar Frey is in research, development, and implementation of innovative 2-D and 3-D (tomographic) synthetic aperture radar (SAR) imaging techniques and interferometric techniques for applications such as 3-D forest mapping, ground deformation monitoring (persistent scatterer interferometry / differential tomography), and profiling the structure of snowpacks, using various radar sensors and platforms (spaceborne, airborne, and ground-based SAR sensors). At Gamma Remote Sensing, Othmar Frey has been active in various national and international research projects, as a PI as well as a co-investigator, and in consulting related to SAR imaging, interferometric and tomographic applications. He is also active in the development of the Gamma Software. In addition to his position with Gamma Remote Sensing he is also a Senior Research Scientist and Lecturer at ETH Zurich, at the Chair of Earth Observation and Remote Sensing.
