The Synergy Of Ers-2 Sar And Radarsat Sar Imagery

Description
Summary:This work investigates the use of multi-source images to classify sea-ice conditions in the South-western Kara Sea, and in doing so simulate the alternating mode which will be available from the ASAR sensor on board Envisat. The unique data set comprises SAR images obtained from both ERS-2 and Radarsat platforms over a 12 hour-period on 23 March 1997, which also provides a high temporal resolution of the sea-ice processes occurring in the region. The results on the investigation show that a high temporal resolution is desirable when monitoring sea-ice, but combining the ERS-2 SAR image with the Radarsat ScanSAR wide B image does not improve the amount of information available about the ice conditions present in the scenes.
