13.3. Vegetation canopy height and vertical structure from SAR data
Interferometric SAR (InSAR) is sensitive to the spatial distribution of vegetation components. It can be used to estimate height and vertical profile of vegetation canopy. In this section, we will first introduce the principle of InSAR technique and then summarize the forest height estimation using the difference of penetration depth between short and long wavelength bands. The third part of this section will describe the principle of retrieval of forest height and vertical structure using PolInSAR technique.
13.3.1. Principle of interferometric SAR
The estimation of forest height using SAR data mainly depends on InSAR technique. The use of InSAR technology requires acquiring ...
