摘要
针对79 GHz频带雷达在雾气、降雨、降雪等不同天气条件下雷达性能下降的问题,研究了基于79 GHz频带车载雷达的传播特性。评价了包括大气因素、降水(雾气、降雨、降雪)以及沙尘对该频段的影响,并仿真分析了该频带在不同环境条件下对车载雷达性能的影响。结果表明,不同天气条件对该频段雷达具有一定的衰减作用,同时降雨对79 GHz车载雷达具有较大的影响。该研究对开发和利用79 GHz频带,并为该频带进一步应用于智能交通系统提供了理论根据。
such as the Radar performance is greatly impacted by atmospheric environment, the propagation characteristics, fading due to atmosphere, frog, rain, snow, and sand are simulated based on 79 GHz frequency band. Radar performance in different weather conditions are also simulated and analyzed. Results show that 79 GHz frequency band radar has a certain attenuation under different weather conditions, and the rainfall is the main influence. This research provides a theoretical basis for further development and utilization of 79 GHz frequency band used in the intelligent transportation system.
