AbstractPolarimetric SAR capability was first demonstrated in the CCRS (Canada Centre for Remote Sensing) airborne SAR facility as an experimental X-band channel. Although this demonstration system had poor channel isolation, techniques were developed to show that under these conditions, it was possible to produce fully calibrated polarimetric data. That system was eventually abandoned in favour of a technically much improved C-band polarimeter. In November, 1996, the facility was transferred to Environment Canada who own and operate the facility. This paper reviews the technical implementation of the C-band polarimeter, the processing and calibration chain, and results from an extended period of stable operations. Calibration for this system involves use of external PARCs and trihedral corner reflectors deployed across the imaging swath. The paper also gives an error budget for the phase and amplitude calibration of the instrument.
