Polarimetric ALOS PALSAR Time Series in Mapping Biomass of Boreal Forests
Here, we examined multitemporal behavior of fully polarimetric SAR (PolSAR) parameters at L-band in relation to the stem volume of boreal forests. The PolSAR parameters were evaluated in terms of their temporal consistency, inter-dependence and suitability for forest stem volume estimation across several seasonal conditions (frozen, thaw and unfrozen). The satellite SAR data were represented by...
متن کاملPolarimetric Calibration of ALOS/PALSAR
This report presents the polarimetric calibration results of ALOS/PALSAR and discusses a stability of polarimetric calibration parameters during the calibration phase of ALOS and an influence of Faraday rotation on them. PALSAR is the first spaceborne polarimetric L-band synthetic aperture radar and its polarimetric data is expected to be utilized in various remote sensing applications. However...
متن کاملInitial Polarimetric Calibration of PALSAR
This paper discusses an initial polarimetric calibration of ALOS PALSAR. ALOS was launched on January 24, 2006. PALSAR, which is one of ALOS three sensors, is the first spaceborne L−band polarimetric synthetic aperture radar. It is expected that PALSAR polarimetric data is used for many applications such as agriculture, forestry, ocean, natural disasters etc. Thus, polarimetric calibration is a...
متن کاملNon-Parametric Retrieval of Aboveground Biomass in Siberian Boreal Forests with ALOS PALSAR Interferometric Coherence and Backscatter Intensity
The main objective of this paper is to investigate the effectiveness of two recently popular non-parametric models for aboveground biomass (AGB) retrieval from Synthetic Aperture Radar (SAR) L-band backscatter intensity and coherence images. An area in Siberian boreal forests was selected for this study. The results demonstrated that relatively high estimation accuracy can be obtained at a spat...
متن کاملSoil Moisture Retrieval from Temporal Series of Palsar Scansar Data
The availability of dense temporal series of SAR acquisitions from space platforms makes possible the use of change detection techniques to monitor near-surface soil moisture content globally. The rational of this method is that temporal changes of surface roughness, canopy structure and vegetation biomass occur at longer temporal scales than soil moisture changes, excluding periods of cultivat...
