摘要

空间碎片目标具有平动、振动、转动等多维运动特征,对其进行多维运动参数的精确探测对于空间碎片编目管理及其再入轨道预测具有重要的意义。本文简述了激光微多普勒探测技术对空间碎片探测的基本原理,并对直径0.01m、0.1m、5m、10m,运动速度8km/s的空间目标有效激光探测距离和探测精度进行了仿真计算。结果表明利用激光微多普勒探测技术,可以对空间碎片实现较远的探测距离、较高的速度分辨率和角速度分辨率,可以实现对空间碎片高精度在轨观测。最后分析了能够实现激光微多普勒雷达在轨应用还需要解决的关键技术。

Abstract

Space targets including space debris have multidimensional motion characteristics such as translation,vibration and rotation.Accurate detection of them has great significance for cataloging management and predicting the reentry orbit of space debris.This paper briefly describes the existing laser micro-Doppler effect detection technology,simulates and calculates the effective detection range and detection accuracy of this technology for space debris with a diameter of 0.01m,0.1m,5m,10m and a moving speed of 8km/s.The results show the laser micro-Doppler effect detection can realize far detection range,high velocity resolution and angular resolution which make it possible to realize high-precision on-orbit observation of space debris.Finally,the key technologies that need to be solved to realize the on-orbit application of laser micro-Doppler LIDAR are analyzed.

Key words： space debris; laser detection; micro-Doppler effect
