Sensitivity study of radar backscatter from boreal forest using discrete scatterer model

Polarimetric SAR decomposition has been expected to be a potential candidate of a tool to measure physical parameters of vegetated fields. For this context, it is important to validate theoretical model quantitatively with well controlled experiment. In this paper, simple boreal forest was modeled based on Discrete scatterer model. Through sensitivity study by using the model, we propose several useful indexes to infer vegetation parameters such as soil moisture. This study will be validated by X-band indoor full polarimetric SAR in Niigata University.
