摘要
基于Rayleigh散射,建立了沙尘媒质中的微波衰减和相移模型,并与Goldhirsh模型、Dong模型计算结果进行了比较和分析。仿真结果表明,衰减模型与Goldhirsh模型、Dong模型比较吻合,相移模型与Dong模型结果一致,验证了提出模型的有效性。
Based on the Rayleigh scattering, the models for microwave attenuation and phase shift for a medium with sand and dust particles were derived. The predictions made with proposed formula were compared with results obtained by Goldhirsh＇ s formula and Dong＇ s formula. Computations show the predicted values from the proposed attenuation formula are in an excellent agreement with the val- ues by Goldhirsh＇ s formula and Dong＇ s formula. The phase shift values calculated by the proposed model are in good agreement with those obtained by Dong＇ s model. The results verified the accuracy and validity of the proposed formulas.
