Estimating Forest Biomass in Temperate Forests Using Airborne Multi-frequency Polarimetric SAR Data

Improvement of Biomass Estimation in Forest Areas based on Polarimetric Parameters Optimization of SETHI airborne Data using Particle Swarm Optimization Method

Estimation of forest biomass has received much attention in recent decades. Airborne and spaceborne (SAR) have a great potential to quantify biomass and structural diversity because of its penetration capability. Polarizations are important elements in SAR systems due to sensitivity of them to backscattering mechanisms and can be useful to estimate biomass. Full Polarimetric Synthetic Aperture ...

Airborne multi-temporal L-band polarimetric SAR data for biomass estimation in semi-arid forests

Correlations between forest biomass and full polarimetric parameters derived from Pi-SAR-L2 data for a site in Riau, Indonesia

Correlations between forest biomass and full polarimetric parameters, including  0 , four-component decomposition, eigenvalue decomposition (entropy/alpha/anisotropy), and coherence values between polarization were analyzed. Polarimetric and interferometric airborne synthetic aperture radar with L-band type-2 (Pi-SAR-L2) data were examined to identify prospective parameters for estimating the ...

Comparison of Forest Parameter Estimation Techniques Using SAR Data

It is important to monitor forests in order to understand the impacts of global climate changes on terrestrial ecosystems. To characterize forest changes, it is useful to parameterize a forest using several parameters, such as biomass, basal area, tree density, tree height, and trunk diameter. These parameters are not independent and some of them are related by allometric equations. Remote sens...
