A first assessment of the radiometric calibration of ALOS PALSAR ScanSAR data was undertaken within the first phase of the ALOS PI project (2007/2008) and covered in the PI report "Assessment of PALSAR ScanSAR calibration and impacts for wetland applications" to JAXA. The study indicated good absolute (temporal) radiometric stability of ScanSAR data (0.26 dB), but strong systematic artefacts (0.6-1.9 dB) in the calibration between the individual scans within the scenes.
The PALSAR antenna pattern was updated in the SIGMASAR processor in July 2008 to address the above anomalies, and the objective of this study is thus to assess the absolute radiometric stability and relative, scan-to-scan, calibration accuracy of PALSAR ScanSAR data processed after the upgrade.
