His professional expertise encompasses radar remote sensing, radar polarimetry, polarimetric
scattering analysis, environmental change detection, polarimetric SAR image analysis for
monitoring the planet earth. He and his group have developed “Four-component scattering power
decomposition” for the utilization of polarimetric SAR image interpretation, which is one of the
essential part of polarimetric SAR development. All kinds of radar technology associated with
wave scattering phenomena are major topics in his laboratory.
