Dual-Pol X-Band Pol-InSAR Time Series of a Greenland Outlet Glacier
The Helheim glacier in south-east Greenland faces a retreat and thinning like many other Greenland outlet glaciers, but showed two particular huge and fast retreats between 2000 and 2005, coinciding with an acceleration of glacier flow [1]. The estimation of glacier retreat and thinning are established procedures based on a variety of remote sensing techniques, e.g. SAR interferometry (InSAR) [...
متن کاملPol-SAR time series for soil moisture estimation under vegetation
In this paper the problem of soil moisture estimation under vegetation is investigated. Pol-SAR inversion algorithms are developed and applied on the multi-temporal AGRISAR data set from 2006 to investigate their potential and limitations over time. Modifications of the model based Freeman decomposition are used to decompose the scattering contributions and to invert the surface and dihedral sc...
متن کاملClassification of Agricultural Sites using Time-series of High- resolution dual-polarisation TerraSAR – X Spotlight images
Increasing demands for lasting and environmentally conscious use of natural resources together with a cost effective and restrictive use of fertilizers and pesticides require the employment of new technologies in agriculture. The preliminary results presented here consist in the automatic land use classification of agricultural fields based on multi-temporal TerraSAR-X images in dual polarizati...
متن کاملClassification and Monitoring of Reed Belts Using Dual-Polarimetric TerraSAR-X Time Series
Synthetic aperture radar polarimetry (PolSAR) and polarimetric decomposition techniques have proven to be useful tools for wetland mapping. In this study we classify reed belts and monitor their phenological changes at a natural lake in northeastern Germany using dual-co-polarized (HH, VV) TerraSAR-X time series. The time series comprises 19 images, acquired between August 2014 and May 2015, in...
متن کاملRetrieval of Rice Phenology by Means of Copolar Dual-pol Images Provided by Terrasar-x
The polarimetric behaviour of rice fields at different phenological stages has been analysed by using time series of TerraSAR-X images. These are X-band copolar dual-pol images available for the whole growth cycle. As plants grow, changes in their morphology produce clear signatures in various polarimetric observables. Based on this sensitivity to phenology, a physically based retrieval approac...
