Title: Backscatter signatures of wind-thrown forest in satellite SAR images
Abstract: Two field experiments have been conducted in Sweden to allow an evaluation of the backscatter signatures of windthrown forest from L-band, C-band and X-band Synthetic Aperture Radar.When the trees are felled the backscattered signal from TerraSAR-X (X-band) increase with about 1.5 dB, while for ALOS PALSAR (L-band) a decrease with the same amount is observed.Radar images with fine spatial resolution also show shadowing effects that should be possible to use for identification of storm felled forest.
