| 摘 要： | 使用微波分光仪构建了分束法测试系统,利用分束法测试了10.5GHz频率下0°～10°铝板、不锈钢板、镀锌铁板的后向散射系数,结果表明金属板的微波后向散射系数随方向角的增加而迅速减小,与理想导体平面的镜面反射特征一致,而且电导率较大的铝板更适合作为分束法的定标板。

| Abstract: | In constructing the beam splitting method system by microwave spectrometer,three metal plate samples,as aluminum sheet,stainless steel sheet,galvanized iron sheet,are tested for the microwave backscattering coefficient with frequency of 10.5 GHz.The changing regulation is found with different angle in range of 0°~10°.Finally,the microwave backscattering coefficient of metal plates reduce rapidly along with the yaw increasing,is consistent with the perfect conductor plane＇s regular reflection characteristic.Moreover,aluminum sheet is more suitable to take the index pad of beam splitting method,for its bigger conductivity. |
