Scattering contribution of randomly distributed single tree species

A complex scattering matrix containing phase information is proposed to establish the Mueller matrix, and then the scattering contribution of the forest vegetation model is solved. Due to the distortion of the signal phase due to the scattering effects of the crown and trunk, the interaction between the vegetation target and the surrounding environment is rarely considered. In this paper, the disk-like and spicule-like particle layer is used as the scattering radiation transmission model of the vegetation canopy, and the vertical thick cylinder is used as the scattering radiation transmission model of the trunk layer. Secondly, the projection mapping algorithm (MPA) is used to calculate the hierarchical vegetation model. This paper studies the scattering and attenuation of randomly distributed single tree target, and evaluates the rationality of using complex scattering matrix to calculate the scattering contribution of vegetation.
