Forest remote sensing on the individual tree level by airborne millimeterwave SAR

This paper presented experimental results discussing the potential of millimeterwave SAR for forest remote sensing on the individual tree level. As can be seen from the experimental results, although there is a certain amount of canopy penetration, a significant part of the signal response is received from the tree crowns. This provides both interesting perspectives for an analysis of forest volumes by continuous TomoSAR models as well as the reconstruction of individual tree models by utilization of discrete TomoSAR models.
