【摘要】 介绍了一套全极化、多频段的微波散射测量装置。系统以矢量网络分析仪为核心,可测量的频率范围为1～12.6GHz,天线角度变化范围为-65～65°。系统采用时域技术和金属板定标方式,通过对不同大小金属板的测量验证了系统的精度和准确度。最后利用该系统测量了水和土壤2类典型地物的散射系数,并结合理论模型实现了土壤参数的反演。更多还原

【Abstract】 A full polarization and multi-band microwave scattering measurement devices are introduced in this paper.Vector network analyzer is the core of the systems that is capable of operation frequency from 1GHz to 12.6 GHz,and changes in the range of the antenna is—65°to 65°.Time-domain technology and metal plate calibration methods are used in the system,and the metal plates of different sizes are measured to verify the precision and accuracy. Finally,the scattering coefficients of water and soil are measured by the system,and combine with the theoretical model to the inversion to achieve the soil parameters.更多还原
