Being negligible for X-band sensors, Faraday rotation is significant in L-band and can reach up to 100° with a pronounced diurnal variation and a strong dependence on solar activity during the 11-year solar cycle. ALOS-2 will continue the L-band SAR … Interferometric synthetic aperture radar (InSAR) data sets from TerraSAR-X, RADARSAT-2 and ALOS-PALSAR are compared for their ability to detect ground movement over the continuous permafrost site of Herschel Island, Yukon Territory, Canada. 0000022256 00000 n Thaw slumps may require a different interferometric approach, such as slump extent mapping from coherence loss, or the installation of corner reflectors and point target techniques. %PDF-1.5 %���� Fine resolution in a … 72 pages. 0000010818 00000 n wavelength of the L-band ALOS PALSAR.

The ability to form long interval displacement products holds the most promise for permafrost monitoring, since long-term trends are of greater interest for permafrost stability than short-term seasonal changes. 0000454480 00000 n 0000021236 00000 n endstream endobj 576 0 obj <>/Size 486/Type/XRef>>stream 0000478344 00000 n All rights reserved.

Collectively, these new sensors offer finer spatial resolution, better baseline control, shorter revisit periods, and a variety of SAR wavelengths not previously readily available. 0000471469 00000 n 0000461413 00000 n ► RADARSAT-2 and PALSAR one year interferograms are useful for permafrost monitoring. 0000016066 00000 n 0000002752 00000 n 0000300576 00000 n ► PALSAR two and three year interferograms can also form good displacement products. In general, InSAR is more successful at identifying broad areas of subtle subsidence in gentle relief, areas of terrain instability, possibly due to permafrost thaw or ground ice melt and the removal of water volume, and prior to significant slumping. 0000015228 00000 n Dabei erörtern wir gemeinsam mit Ihnen Ihre Fragestellungen und beraten Sie in der Konzeption Ihrer Prozesse. 0000461782 00000 n Stacking is advantageous for the TerraSAR-X and RADARSAT-2 data sets, although mottling, possibly an interaction of the SAR with vegetation, or residual tropospheric noise, is visible, reducing the reliability of the results. Current version published October 30, 2008. The capacity of the radar, the PALSAR-2 of the ALOS-2, has been significantly improved form the ALOS’s PALSAR in all aspects including resolution, observation band, and time lag for data provision. x�b``�e`�|����0E�A�D؀�,�D&�I_�S��útEb �cc+�b�?�pN��^%��[�|������jφ �ݪ�'��ll�t�����Ô����R�0X���''�������{�\�k�N=�d���KhhhZFGGG��dai@ ��OP�)(���3��| 577 0 obj <>stream After the successful launch JAXA is currently performing early functional check-outs.
