Curriculum Vitæ – Othmar Frey

Name: Othmar Frey
Profession: Engineer (M.Sc. ETH), Dr. sc. nat.
Responsibility within Gamma: Project Scientist

Key Qualifications
The main experience of Othmar Frey is in the development and implementation of SAR imaging algorithms, mainly for airborne SAR. His research activities have included development, implementation, and analysis of processing algorithms for  airborne SAR imaging, SAR tomography, SAR interferometry, SAR geocoding, as well as, analysis of error sources in SAR data products. His more general background is in geomatics engineering including geodesy, navigation/GPS signal processing, photogrammetry and remote sensing, parameter estimation, 3-D computer graphics, geo-information systems, and geostatistics.

At Gamma Remote Sensing, Othmar Frey is currently very active in the development of the Gamma software. Further activities include research and consulting related to SAR processing, as well as interferometric data processing.
