Abstract

Possibility of application of orbital lidars for laser detection of gas leaks from orbital vehicles has been considered. The optical characteristics of the main light-scattering components – molecules and atoms of gases, free electrons, aerosols, and space garbage are estimated at altitudes of 100–500 km from the Earth surface. Based on equations of laser sensing and laser detection and ranging, the lidar return signal powers are calculated. It has been shown that an orbital lidar with modern technical parameters can reliably detect signals from dispersed components in space at distances of several hundred meters from an orbital vehicle. Nowadays this problem becomes relevant in view of the Soyuz spacecraft sprung a leak on December 15, 2022 sending streams of coolant into space. The results of calculations have also shown that that space garbage can be detected with a space lidar at distances from several units to tens of kilometers.
