Stem volume retrieval at stand level using multiple low-frequency SAR images
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2003

In this paper the ground slope effect on stem volume retrieval from VHF-band SAR images has been studied using multiple co-registered images acquired from different flight headings. Accurate measurements of the topography were used as additional input data to a model of the backscatter amplitude variation with ground slope and aspect angle. Modeling this topographical effect on the radar backscatter provides a base for improvement of the stem volume retrieval
