论文摘要
在将目标定位为单立与单台的背景下，这一贡献着重于有关单场反射提供的位置，方向和时钟偏移的渔民信息。通过虚拟锚位置的先验分布考虑了对目标环境的先验知识的可用性，并研究了提供信息的等级，强度和方向。我们表明，当没有任何先验知识可用时，单反射反射在与反射表面平行的方向上提供位置信息，而与目标的位置无关。我们对结果提供了几何直观的解释，并提供了证明其潜在影响的数值示例。
In the context of positioning a target with a single-anchor, this contribution focuses on the Fisher information about the position, orientation and clock offset of the target provided by single-bounce reflections. The availability of prior knowledge of the target's environment is taken into account via a prior distribution of the position of virtual anchors, and the rank, intensity and direction of provided information is studied. We show that when no prior knowledge is available, single-bounce reflections offer position information in the direction parallel to the reflecting surface, irrespective of the target's and anchor's locations. We provide a geometrically intuitive explanation of the results and present numerical examples demonstrating their potential implications.
