  • In microwave remote sensing quantitative study, it needs to know dielectric properties of remote sensing objects precisely. The free-space method was used to in situ measure typical objects permittivities in the fields for obtaining precise data of fitting for remote sensing real objects. The basis and calibration method of free-space method were given. The permittvities of black soil, meadow, and ice with the method were presented. The results were analysed.
