IGARSS 2010 - 2010 IEEE International Geoscience and Remote Sensing Symposium - July 25 - 30, 2010 - Honolulu, Hawaii, USA

FD-3: SAR Polarimetry: Basics, Processing Techniques and Application

Sunday, July 25, 08:30 - 17:30

Presented by

Eric Pottier, Jong-Sen Lee


Several space borne Polarimetric Synthetic Aperture Radar (PolSAR) systems are in operation since 2006: ALOS/PALSAR (L-band) launched in January 2006, TerraSAR-X (X-Band) launched in June 2007, and RADARSAT-2 (C-Band) launched in December 2007.

For the first time, the availability of spaceborne PolSAR data will provide an unprecedented opportunity for applying advanced PolSAR information processing techniques to the important tasks of environmental monitoring. PolSAR remote sensing offers an efficient and reliable means of collecting information required to extract geophysical and biophysical parameters from Earth’s surface. This remote sensing technique has found many successful applications in crop monitoring and damage assessment, in forestry clear cut mapping, deforestation and burn mapping, in land surface structure (geology) land cover (biomass) and land use, in hydrology (soil moisture, flood delineation), in sea ice monitoring, in oceans and coastal monitoring (oil spill detection) etc.

SAR Polarimetry represents today a very active area of research in Radar Remote Sensing, and it becomes important to train and prepare the future generation of researchers to this very important topic.

The aim of this tutorial is to provide a substantial and balanced introduction to the basic theory, scattering concepts, systems and advanced concepts, and applications typical to radar polarimetric remote sensing. This tutorial on SAR polarimetry touches several subjects: basic theory, scattering modeling, data representations, target decompositions, speckle filtering, terrain and land-use classification, man-made target analysis, etc. This lecture will be illustrated by ALOS-PALSAR, TerraSAR-X and RADARSAT-2 polarimetric SAR images. The connection to polarimetric SAR interferometry will be also briefly reviewed.

This lecture is intended to scientists, engineers and students engaged in the fields of Radar Remote Sensing and interested in Polarimetric SAR image analysis and applications. Some background in SAR processing techniques and microwave scattering would be an advantage and familiarity in matrix algebra is required.

After graduated from Harvard, he joined US Naval Research Laboratory (NRL) as an electronics engineer. He retired in 2006 after 37 years service as the Head of the Image Science Section, Remote Sensing Division. Upon his retirement, he received the distinguished Navy Meritorious Civilian Service Award for his significant and sustained contributions toward SAR and polarimetric SAR research. Each year at NRL, only one or two researchers receive this distinguished award.
