New earth observation scenario using the ALOS-2 with the L-band high-resolution and full-polarimetric SAR

During more than 20 years JAXA history on spaceborne and airborne SAR, L-band SAR has been adopted under the unique mission goal, i.e., the global observation. Over the JERS-1 SAR´s essential findings on the surface deformation and the deforestation monitoring, both of which owe to the signal penetration of vegetation at L-band, ALOS has achieved the wider and more comprehensive global understanding of the earth phenomena covering four spheres, i.e., largely biosphere, geosphere, cryosphere, and the hydrosphere, and it also contributed the disaster monitoring. On the other way, the airborne SAR has been developed and utilized for investigating the future technology development and the applications, i.e., polarimetric application and the interferometric application.
