| Outline of Final Research Achievements |
The estimation of ice thickness using Synthetic Aperture Radar (SAR) data needs to precisely extract the dielectric constants of ice surface derived from its backscattering coefficient. However, the direct obaservation of dielectric constant is difficult for in-situ measurement outsides because an instrument to measure is expensive and less portability of conventional one. We recently can choose a portable Vector Network Analyzer (VNA) for outside measurements with carrying easily. The microwave measurement method of dielectric constants based on free space method can be considered to be applied to targets of snow and ice. Therefore, this study eastablished a system for dielectric constants measurement which was used portable VNA and with free space method. Our system was applied to measurements the dielectric constants of sea ice surface directly, and the results showed reasonable estimations of dielectric constants.
