由于自动驾驶和安全执法技术的发展，车辆环境中的无线电应用变得越来越流行，这些技术利用了车辆到车辆、车辆到基础设施以及雷达解决方案。由于各种各样的可能的环境配置，并高度动态特性的环境，特定的确定性的无线电传播模型必须开发，以协助设计和模拟这样的车辆应用。在目前的工作中，我们提出了一个动态的射线跟踪模型，可以提供一个多维的信道预测，包括多普勒频移，与一个合适的“动态环境数据库”，描述了一个场景与移动的对象和终端的基础上运行。所提出的方法适用于一个参考街道峡谷的情况下，一个大的移动对象，代表一辆公共汽车产生现实的信道的功率多普勒轮廓的估计。
Radio applications in vehicular environment are becoming popular due to the development of autonomous driving and safety enforcement technologies that make use of vehicle-to-vehicle, vehicle-to-infrastructure as well as of radar solutions. Due the large variety of possible environment configurations, and to the highly dynamic characteristics of the environment, specific deterministic radio propagation models must be developed to assist the design and simulation of such vehicular applications. In the present work we present a dynamic ray tracing model that can provide a multidimensional channel prediction, including Doppler’s shifts, with a single run on the base of a suitable “dynamic environment database” that describes a scene with moving objects and terminals. The proposed approach applied to a reference street canyon scenario with a large moving object representing a bus is shown to yield realistic estimates of the channel’s power-Doppler profiles.
