Curriculum Vitæ - Charles L. Werner

Name: Charles L. Werner
Profession: Engineer, Dr. phil. nat.
Responsibility: Vice-president of Executive Board and Senior Project Scientist


Key Qualifications
The main experience of C. Werner is in the design, construction, applications of SAR systems as well as the development of SAR processing and SAR interferometric software. Currently he is very active in SAR interferometric data processing and the development of applications of single-pass as well as repeat- pass SAR interferometry for topographic mapping, differential motion, land-use classification, and the retrieval of geophysical and biophysical parameters over land (including forestry, agricultural, and hydrological applications).

Activities included: High accuracy automated calculation of ERS-1 interferograms, Geocoding of ERS-1 interferometric digital elevation model (DEM) data. Modeling of interferometric coherence signatures of forests for determination of biomass. Estimation of surface slopes directly from SAR interferometric phase data, correction of SAR backscatter and interferometric correlation for slope Designing and implementation of a SAR processor for airborne SAR of sub-meter resolution airborne and space-borne sensors
1982 - 1992 Member Technical Staff at the Jet Propulsion Laboratory, Pasadena, CA. Activities included: Studied methods for absolute and relative radiometric and polarimetric calibration of aircraft and spacecraft SAR data. Developed a calibrated multi-polarization L- and C- band SAR processor for the JPL AIRSAR instrument. Proposed Huygens probe sounder/altimeter for the measurement of the ocean depth and stratigraphy of Titan. Designed the microwave radiometer for the Cassini mission to measure the dielectric constant and emissivity of the Titan surface. Co-investigator for the Shuttle Imaging Radar-C (SIR-C) mission involved with the interferometric, bistatic and external calibration experiments. Designed and implemented a bistatic SAR processor for ERS-1 with echo reception by the JPL DC-8. Developed improved algorithms for phase-unwrapping of SAR interferograms. Studying the use of multiple-pass SAR interferometry for detection of micro-topographic change associated with freezing and thawing of the permafrost using ERS-1 data and seismic displacements System engineer for the Cassini Radar, responsible for the multiple-beam burst-mode SAR system design. Performed the system design of the Cassini Radar Block Adaptive Quantizer (BAQ). Developed a system for generation of topographic maps from ERS-1 multiple pass interferometric SAR data including interferogram generation, phase unwrapping, height measurement and image rectification.
1977 - 1982 Technical Staff at University of Pennsylvania. Activities included: Developed a computer-controlled three-dimensional microwave imaging facility utilizing both frequency and polarization diversity.
