Scattering phase center (SPC) location in boreal forests was studied in order to assist forest inventory with singleand quad-pol synthetic aperture radar (SAR) interferometry. Airborne Xand L-band interferometric SAR data collected by the DLR E-SAR instrument in southern Finland during the FINSAR campaign was used in the study. A simple Random Volume over(More)
This paper discusses the possibility to use spaceborne X-band radar interferometry for forest height mapping. In our previous works was shown that airborne X-band SAR interferometry combined with accurate ground elevation model can provide good estimates of boreal forest height. In order to apply this technique to spaceborne SAR images, temporal variability(More)
This work investigates applicability of spaceborne repeat-pass interferometric SAR images for detecting mowing events on agricultural fields. Four pairs of one-day repeat-pass COSMO-SkyMed acquisitions were analysed and compared to in situ measurements of 11 agricultural grasslands to study the potential of X-band temporal interferometric coherence for(More)
This paper evaluates performance of fully polarimetric SAR (PolSAR) data in several land cover mapping studies in the boreal forest environment, taking advantage of the high canopy penetration capability at L-band. The studies included multiclass land cover mapping, forest–nonforest delineation, and classification of soil type under vegetation. PolSAR data(More)
This letter describes an algorithm development for the production of a large-scale fully polarimetric synthetic aperture radar (SAR) (PolSAR) mosaic using multitemporal Advanced Land Observing Satellite Phased Array type L-band SAR acquisitions. The PolSAR data were collected during the snow-melting season in 2007 over Finnish Lapland, resulting in(More)
