摘要：Synthetic aperture radar tomography (TomoSAR) has been proved to be able to reconstruct 3D reflectance of volumetric targets, such as vegetation. It gives us an opportunity and a possibility to monitor forest pest through extracting 3D structural information of the forest. In this paper, TomoSAR echo data of normal and pest forest are simulated with PolSAR Pro at L-band before and after the pest respectively, after analysing physical geometry and backscattering properties of forest pest and disease. Then, a method used for extracting 3D structure information of the forest is presented and discussed. Finally, differences between the normal and pest forest are demonstrated and analyzed with the TomoSAR imaging results.
