The CEOS SAR calibration network – SARCalNet

Abstract:
SARCalNet is an initiative of the SAR subgroup of the Working Group on Calibration and Validation (WGCV) of the Committee on Earth Observation Satellites (CEOS). Development of SARCalNet began in 2020, based upon a longstanding and existing target database of calibration targets contributed to this same group. When fully implemented, SARCalNet will provide a pre-defined set of information about SAR calibration targets, both natural and artificial, to facilitate joint calibration and performance evaluations between sensors as well as post-launch Cal/Val of any operating SAR sensor data operating at typical SAR frequencies and polarizations. When possible, SARCalNet will also provide access to the calibration data sets that were used to either calibrate or monitor calibration and performance of specific sensors.
