Rice Monitoring Using Touzi Decomposition Based on Polarimetric SAR Data in Southwestern China

摘要

Rice is one of the three largest food grains in the world, providing food for more than one third of globe population. Researches on rice monitoring are of great significance and attract more attention of radar remote sensing communities. In this study, the Touzi target decomposition was investigated for rice monitoring. The results showed that the parameters of Touzi decomposition were sensitive to rice fields, especially the dominant symmetric scattering type amplitude. In addition, the dominant symmetric scattering type phase was the most sensitive to rice growth change and was very promising for rice monitoring.
