Precise DEMs at high spatial resolution are indispensable for a variety of scientific studies and applications. Presently, the TanDEM-X mission possesses the capability to collect global-scale InSAR data at high spatial resolution, enabling the generation of a high-resolution global DEM (12 m). Nevertheless, directly utilizing InSAR data poses challenges in detecting sub-canopy topography within forest areas, due to the presence of volume scattering and limited penetration of X-band. Conversely, the upcoming BIOMASS mission operated in P-band will provide an exceptional opportunity for sub-can...
