Abstract :
Evaluating the accuracy of a scanning radar altimeter for forest inventory is problematic, as no feasible radars exist, and the ground truth data collected by conventional means is often not accurate enough. In this paper, a simulation method, J. Hyyppa (1993), for optimizing the technical parameters of a scanning radar altimeter and evaluating the radar´s accuracy for forest inventory is described. The method is based on statistical information of boreal forest stands, radar-derived stand profiles and simulation
