Radar image acquired by the F-SAR system over the Pongara National Park south of Libreville, Gabon
In Pongara National Park, there are still large areas of pristine mangrove forest, while the inland borders merge into dense rainforest. The colour scheme shows different types of reflection of the radar signals. For signals in the L band (23 centimetre wavelength) mainly vegetation-free surfaces (for example, water or open fields) appear blue in the image. A dominant double reflection (for example, from the vertical mangrove trees followed by the water surface) appears red. A predominantly omnidirectional reflection, especially from the volume of the rainforest treetops appears green.
