Rice Crop Monitoring Using ENVISAT-1/ASAR

摘要

Hiroshima Institute of Technology (HIT) is operating the direct down-link of ENVISAT-1/ASAR in Japan. This study focuses on the validation for rice crop monitoring by means of multi-temporal and multi-angle ASAR alternating cross polarization mode (VV/VH) images over several passes. In this study, the validation is performed by means of overlaying Sigma-Nought (σ0) images in the above each mode captured during the rice growing cycle with ground truth measurements such as height of crop, ratio of crop vegetation cover and leaf area index (LAI). As the result of this study, it is indicated that the growth process of rice crop can be estimated by means of multi-temporal and multi-angle ASAR alternating cross polarization data.
