论文摘要
在同伴文章中，我们讨论了一种新的被动光学传感技术，时空投影光学断层扫描（SPOT）的辐射敏感性和分辨率，以检测和跟踪子CM以及更大的空间碎片，以实现空间情境意识。斑点基于以下原则：如果假设点源的相位轨迹在非常宽的望远镜视野中可以预测，则可以实现长期的合成暴露。本文讨论了碎片挖掘的计算搜索空间以及基于轨道确定的广义霍夫变换的递归度量和拟合算法。
In a companion article, we discussed the radiometric sensitivity and resolution of a new passive optical sensing technique, Space-Time Projection Optical Tomography (SPOT), to detect and track sub-cm and larger space debris for Space Situational Awareness. SPOT is based on the principle that long synthetic exposure can be achieved if the phase-space trajectory of a hypothetical point-source is precisely predictable within a very wide telescope field-of-view, which is the case for orbiting debris. This article discusses the computational search space for debris mining as well as a recursive measure-and-fit algorithm based on a generalized Hough transform for orbit determination.
