Abstract
Though ladar and stereo have received far more attention for UGV navigation use, radar offers some unique benefits. Many radar systems have the ability to partially penetrate thin vegetation, fog, smoke, and other obscurants while detecting hidden solid obstacles. Also, some systems provide useful information in addition to range; for example, Doppler radars measure target relative velocities as well. Weaknesses of radar-based sensing systems (such as limited angular resolution and erratic readings due to specular reflections) are generally quite different than those of stereo or ladar, so that radar data can be particularly useful when fused with another sensing modality. Further, a number of inexpensive radar units are currently commercially available, marketed primarily as automotive driver warning systems. This proposal describes an effort to combine some of the unique advantages of radar with more widely-used ranging devices for UGV applications. Phase I work aims to design and partially implement a UGV perception system, using a COTS radar unit, to merge radar sensor data with ladar in real time to generate useful terrain characterizations for autonomous navigation. Also included is a Phase I option for modifying this design to support stereo data.
