The invention discloses a radar-based train positioning method and device. The train positioning method comprises the following steps: pre-constructing a radar scattering feature map; acquiring a current local environment map based on the current echo data of the radar; and matching and comparing the current local environment map with the radar scattering characteristic map to calculate the current position of the train. According to the method, the real-time positioning precision of the train is improved, and positioning auxiliary equipment beside the track is effectively reduced, so that theconstruction cost and the maintenance cost of train positioning are effectively reduced, the real-time detection of the road condition environment is realized, and the safety and the reliability of train operation are further improved.
本发明公开了一种基于雷达的列车定位方法及装置,列车定位方法包括以下步骤:预构建雷达散射特征地图;基于雷达的当前回波数据获取当前局部环境地图;以及,将所述当前局部环境地图与所述雷达散射特征地图进行匹配对比,以解算出列车的当前位置。本发明提升了列车的实时定位精度,有效地减少了轨道旁定位辅助设备,从而有效地降低了列车定位的施工成本和维护成本,而且实现了路况环境的实时检测,进而提升了列车运营的安全可靠性。
