摘要翻译：
电动轮椅使用者每天都遇到行动障碍。进入无障碍区域的建筑会极大地影响与用户移动性相关的活动。有一些商业设备和一些实验性的设备可以爬楼梯，例如使用带有关节的自适应轮子或毛毛虫驱动。这些系统依赖于传感和控制的使用。为了安全地自动越障，必须对周围环境进行鲁棒的不变检测。雷达可能被证明是一种合适的传感器，因为它有能力处理恶劣的室外环境条件。本文介绍了一种基于反射镜的二维调频连续波(FMCW)雷达楼梯检测扫描仪。提出了一种基于雷达图像的楼梯尺寸标注方法，并在实验室和实际条件下进行了验证。

英文摘要：
  Powered wheelchair users encounter barriers to their mobility everyday. Entering a building with non barrier-free areas can massively impact the user mobility related activities. There are a few commercial devices and some experimental that can climb stairs using for instance adaptive wheels with joints or caterpillar drive. These systems rely on the use for sensing and control. For safe automated obstacle crossing, a robust and environment invariant detection of the surrounding is necessary. Radar may prove to be a suitable sensor for its capability to handle harsh outdoor environmental conditions. In this paper, we introduce a mirror based two dimensional Frequency-Modulated Continuous-Wave (FMCW) radar scanner for stair detection. A radar image based stair dimensioning approach is presented and tested under laboratory and realistic conditions.
