Over the past decade, the development of autonomous vehicles has become central to the growth strategy of**every major international vehicle manufacturer and transportation service provider. However, self-driving cars**are not yet widely deployed on public roads - this is due, in part, to a lack of cost-effective, highly reliable,**all-weather sensing systems. Standard positioning sensors, including Global Navigation Satellite System**(GNSS) receivers, are not accurate enough to keep a vehicle in the centre of its lane, for example.**This project, carried out in cooperation with Havelaar Canada Industrial R & D Laboratory Ltd., will develop**an alternative sensing technology for autonomous navigation based on ground-penetrating radar (GPR). GPR**operates by scanning for subsurface structure; identifiable features below ground remain largely static over**long periods of time, and are not obscured by snow cover, for example. Thus, GPR maps can serve as reliable**localization aids in cases where standard navigation systems fail. The addition of a low-cost and low-power**GPR array to Havelaar vehicles would potentially allow for autonomous operation year-round in Canada. As**part of the project, a prototype GPR localization system will be designed, built, and tested over three seasons**(and a freeze-thaw cycle).**Other

在过去的十年中，自动驾驶汽车的发展已成为各大国际汽车制造商和运输服务提供商增长战略的核心。然而，自动驾驶汽车**尚未在公共道路上广泛部署——部分原因是缺乏经济高效、高度可靠的**全天候传感系统。例如，包括全球导航卫星系统** (GNSS) 接收器在内的标准定位传感器不够精确，无法将车辆保持在车道中央。**该项目与哈弗拉尔加拿大工业研发实验室有限公司合作开展，将开发**一种基于探地雷达 (GPR) 的自主导航替代传感技术。探地雷达**通过扫描地下结构进行操作；例如，地下可识别的特征在很长一段时间内基本上保持静止，并且不会被积雪遮挡。因此，在标准导航系统出现故障的情况下，探地雷达地图可以作为可靠的**定位辅助工具。为 Havelaar 车辆添加低成本、低功耗 ** GPR 阵列将有可能在加拿大实现全年自动驾驶。作为**该项目的一部分，将设计、建造原型探地雷达定位系统，并在三个季节**（以及冻融周期）进行测试。**其他
