PALSAR Radiometric and Geometric Calibration

IEEE Transactions on Geoscience and Remote Sensing, 2009
This paper summarizes the results obtained from geometric and radiometric calibrations of the Phased-Array L-Band Synthetic Aperture Radar (PALSAR) on the Advanced Land Observing Satellite, which has been in space for three years. All of the imaging modes of the PALSAR, i.e., single, dual, and full polarimetric strip modes and scanning synthetic ...

Calibration and validation of PALSAR

IEEE International Geoscience and Remote Sensing Symposium, 2003
This paper introduces preliminary CAL/VAL of the Phased Array type of L-band Synthetic Aperture Radar (PALSAR) onboard the Advanced Land Observing Satellite (ALOS) in terms of the antenna pattern error distribution and the image correlation using the PALSAR parameters.

Polarimetric PALSAR Calibration

IEEE Transactions on Geoscience and Remote Sensing, 2009
Polarimetric Phased-Array-type L-band Synthetic Aperture Radar (PALSAR) system parameters are assessed using data sets collected over several calibration sites. The data collected over the Amazonian rain forest help validate the hypothesis that Faraday rotation is zero near the equator.

PALSAR Characterization and Initial Calibration

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
This paper describes the initial results of the PALSAR characterization using the data acquired in the commissioning phase for the five modes of FBS, FBD, DSN, SCANSAR and POL, and using the active radar calibrator deployed at the calibration site in Japan.
