BIOMASS radar image – The Amazon river in the Brazilian state of Pará
The river and all bodies of water in the scene appear blue. The red hue in the forested areas on both sides of the river indicates significant ground-trunk interaction beneath the canopy – visible due to the penetration ability of the P-band radar.
Polarimetric HSI representation (hue, saturation, intensity): The colour (hue component) indicates the type of scattering mechanism. Blue colours represent surface-like scatterers (like bare ground), green tones represent dipole-like scatterers (such as vegetation or volumetric scatterers) and red colours indicate dihedral-like scatterers (such as interactions between ground and tree trunks in forests or between ground and building walls in urban areas). These images and results were produced as part of the ESA-funded 'ESA Biomass In-Orbit Commissioning' project. All radar images were processed by DLR.
