罗伯特·博世公司进行了“湿天线对毫米波传播的影响”实验，以分析汽车雷达传感器的部分和全部信号退化。结果表明，雨雪天气条件下，天线透镜或天线罩表面水膜的存在是导致高频雷达敏感器性能下降的主要原因。然而，通过适当的天线透镜或天线罩设计，可以在一定程度上抑制水膜的形成，降低其对雷达性能的影响。本文讨论的结果表明，这样的性能限制，一般必须考虑的汽车远程雷达设计师。博世在其新一代汽车远程雷达传感器中成功实施了适当的技术。
The experiment "wet antenna effects on millimetre wave propagation" is carried out at the Robert Bosch GmbH, to analyse the partial and total signal degradation of automotive radar sensors. It reveals that, the existence of water film on the surface of antenna lens or its radome is the main cause for weak performance of radar sensors, operating at high frequencies in rainy and snowy weather conditions. However, it is possible to repress the formation of water film with proper antenna lens or radome design to a certain extent, to reduce its effect on the radar performance. The results, which are discussed in this paper, show that such performance limitation has to be generally taken into account by the automotive long range radar designers. Bosch has successfully implemented appropriate technology in its new generation automotive long range radar sensor.
