摘要

摘要。在实验室中，利用合成孔径雷达装置对汽车77 GHz频段的路面毫米波散射进行了分析。通过这种设置，研究了两种不同表面条件下的混凝土道路样本，确定了材料成分和表面结构对反射率的影响。然后，使用概率密度函数拟合这些变化的分布，即正态分布和瑞利分布拟合。因此，混凝土路面的扩散散射特性可以用数学方法来描述。此外，对先前提出的多孔沥青路面进行了比较和类似的拟合，以获得德国所有常见路面散射的总结。此外，通过分析特定生成的参考样品来验证测量和处理。

MmWave scattering properties of roads on rough asphalt and concrete surfaces

Abstract. In this work, a synthetic aperture radar setup is used for analyzing the mmWave scattering of road surfaces in the automotive 77 GHz band in the laboratory. With this setup, samples of concrete roads in two different surface conditions are investigated, determining the variances in reflectivity depending on material composition and surface structure. Afterward, the distribution of these variations is fitted using probability density functions, namely normal and rayleigh distribution fits. Consequently, the diffuse scattering behavior of concrete roads can be described mathematically. Additionally, previously presented porous asphalt roads are compared and fitted analogously to get a summary of the scattering for all common road surfaces in Germany. Furthermore, a validation of the measurement and the processing by analyzing particularly generated reference samples is performed.
