This document describes a radar detection-based vehicle positioning method and system. Radar localization begins from building a radar reference map. Different techniques as described herein may be used to generate and update radar reference maps. Once a radar reference map is available, real-time localization may be achieved using inexpensive radar sensors and navigation systems. Using the techniques described in this document, data from radar sensors and navigation systems may be processed to identify stationary positioning objects or landmarks in the vicinity of the vehicle. Comparing landmark data originating from on-board sensors and systems of a vehicle to detailed landmark data in a radar reference map may generate an accurate pose of the vehicle in its environment. By using an inexpensive radar system and a less-mass navigation system, a highly accurate vehicle pose can be obtained in a cost-effective manner. 本文档描述了基于雷达检测的交通工具定位方法和系统。雷达定位从构建雷达参考地图开始。可以使用如本文所述的不同技术来生成和更新雷达参考地图。一旦雷达参考地图可用，就可以使用便宜的雷达传感器和
