Forest Change Analysis by means of Pol-InSAR Measurements at L- and P-band

Abstract

This work focuses on the detection and interpretation of forest structural changes by exploiting Pol-InSAR acquisitions. Following a two-layer model assumption, the response from the forest canopy can be decomposed into ground and volume layers. A polarimetric change analysis can be applied over the separated ground and volume scattering components acquired at different times. The analysis of the forest (structural) changes is carried out by exploiting L- and P-band data acquired by DLR’s F-SAR sensor over the Traunstein forest during the TMPSAR campaign. Results corroborate that the decomposition of the forest into simpler layers eases the interpretation of the changes.
