Abstract

ERS-1 SAR interferometry has a large potential to map out forested areas. Different coherence maps show a stable pattern, even with high wind speeds and melting temperatures on the ground. With a DEM of the ground, ERS-1 SAR interferometry can be used to measure interferometric tree heights in a forest. Measurements yield a tree height even when the coherence is low, but have a tendency to decrease with the area coherence. Two boreal forests have been measured showing an interferometric tree height about half of what was measured in-situ. The fact that interferometric measurements are lower than the real tree heights may have been caused by either high wind speeds lowering the effective stable scattering center in the trees or by existence of a ground contribution to the forest backscatter of the radar return.
