Scattering verification and imaging of vegetation and its components
The scattering of a 3-D deterministic forest scene is calculated for simulating the synthetic aperture radar(SAR) image. The generated trees are simplified as a cluster of slim cylinders and disks with the deterministic location, orientation and dielectric constant, which are used for coherent scattering calculation. To ensure the accuracy of coherent scattering calculation, the validity of the generalized Rayleigh-Gans (GRG) approximation and the infinite cylinder approximation are verified. The scattering of tree's components is verified by comparing the imaging results of the calculated data and the simulated data.
