摘要

空间碎片激光测距（DLR）是一种测量绕地球轨道上失效卫星、火箭体或其他空间目标的距离的技术。概率分析表明，DLR成功概率低的原因之一是目标轨道预测不准确。然后，提出使用在自动可恢复距离无门模式下运行的超导纳米线单光子探测器（SNSPD），在这种情况下，目标轨道预测的准确性对DLR成功概率的影响大大降低。通过这种方式，成功探测到249个空间碎片，获得532次数据。探测到的最小目标是轨道高度约1000公里、雷达截面积0.0446平方米的空间碎片（902）。探测到的最远目标是大椭圆轨道的空间碎片（12445），RCS为18.2505 m2，其中2019年1月27日测得的弧段法向点（NPT）范围为6260.805 km。

Space Debris Laser Ranging with range-gate-free Superconducting Nanowire Single-Photon Detector

Space Debris Laser Ranging (DLR) is a technique to measure range to defunct satellites, rocket bodies or other space targets in orbits around Earth. The analysis on the probability shows that one of the reasons for the low success probability of DLR is the inaccurate orbital prediction of targets. Then it is proposed to use the Superconducting Nanowire Single-Photon Detector (SNSPD) running in automatic-recoverable range-gate-free mode, in which case, the effect of the accuracy of the target’s orbital prediction on the success probability of DLR is greatly reduced. In this way, 249 space debris were successfully detected and 532 passes of data were obtained. The smallest target detected was the space-debris (902) with an orbital altitude of about 1000 km and a Radar Cross Section (RCS) of 0.0446 m2. The farthest target detected was the space-debris (12445) with a large elliptical orbit and an RCS of 18.2505 m2, of which the range of the normal point (NPT) of the measured arc-segment on January 27, 2019 was 6260.805 km.

期刊介绍： Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry. Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research. The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics. The journal covers both fundamental and applied topics, including but not limited to: Classical and quantum optics Light/matter interaction Optical communication Micro- and nanooptics Nonlinear optical phenomena Optical materials Optical metrology Optical spectroscopy Colour research Nano and metamaterials Modern photonics technology Optical engineering, design and instrumentation Optical applications in bio-physics and medicine Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
