Multiscale Analysis of InSAR Phase Measurements for Forest Structure Characterization DLR, Germany Assessing 3D forest structure is essential, as it reflects forest condition and state, offering critical insights into forest development when analysed at relevant spatial resolutions. The scale of observation plays a critical role, since natural, anthropogenic, and climate driven disturbances affect 3D forest structure at varying spatial scales. 3D radar-based methods, such as SAR interferometry, provide a promising approach by exploiting sensitivity to the underlying 3D reflectivity. TanDEM-X with its high spatial resolution allows characterization of structural heterogeneity at fine scales by analysing the centroid of the reflectivity profile. To assess forest structural variation across scales, a multi-resolution wavelet analysis is applied. Spatial heterogeneity is quantified using wavelet-based parameters such as variance and entropy. Results from a temperate forest are analysed and compared with airborne LiDAR-derived structural metrics and forest inventory data. Finally, the effects of the interferometric coherence level and topography on the wavelet results are addressed. | |
