摘要

研究了应用轨道激光雷达探测航天器气体泄漏的前景。在距离地球表面 100-600 公里的高度，对主要光散射成分--气体分子和原子--的光学特性进行了估计。结果表明，具有现代技术参数的轨道激光雷达可以可靠地探测到距离航天器几十米到一百米的分散气体泄漏成分的信号。

Prospects for Laser Sensing of Gas Leaks from Spacecrafts

Prospects for the application of orbital lidars for the detection of gas leaks from spacecrafts are investigated. The optical characteristics of the main light-scattering components – molecules and atoms of gases, are estimated at altitudes of 100–600 km from the Earth surface. It is shown that an orbital lidar with modern technical parameters can reliably detect signals from dispersed gas leak components at distances from several tens to one hundred meters from the spacecraft.
