地杂波后向散射系数经验模型研究

Research on the Experience Model of Ground Clutter Backscatter Coefficient

后向散射系数是地杂波性质研究中一个重要的概念,文章介绍了Ulaby后向散射系数和Kulemin后向散射系数经验模型,并且用上述两种经验模型对地面和草地的毫米波段实验数据进行了数据拟合,通过仿真证明上述两种经验模型与实测数据有很好的吻合性,可为毫米波雷达设计提供理论依据。

Backscatter coefficient is one of the important concept in the researching properties of the ground clutter, this paper introduces experience models about the Ulaby Backscatter coefficient and the Kulemin Backscatter coefficient. Then use the above two experience models to data-fitting with the experimental millimeter-waves date of ground and grassland, through the simulation shows that the two experience models are consistent with the Experimental data very well. so that it can provide theoretical basis for design of the millimeter wave radar.
