Abstract :
This paper assesses factors, which affect tree height retrieval using SAR phase coherence due to the heterogeneity within the forest stand. Factors such as edge effects, density, crown shape, slope, and emergent trees are assessed using a Polarimetric Radar Interferometry Simulator (PRIS). Results from the model simulation are compared to actual retrieved height from X-band Intermap data over pine plantations
