Abstract

The lidar device as part of the meteorological complex of the ExoMars-2022 landing platform is designed to study Martian aerosol, the planetary boundary layer, and small-scale atmospheric turbulence. A miniature lidar based on a pulsed semiconductor laser and an avalanche photodiode in the photon counting mode will make it possible to obtain aerosol backscattering profiles along a vertical path from 10 to 1500 m during the day and from 15 to 10 000 m at night. In the passive mode, the sky brightness is measured in a narrow spectral range and in a narrow solid angle with a frequency of up to hundreds of hertz. The measured fluctuations can provide information about the turbulence of the daytime atmosphere and its relation to dust activity. In the paper we considered the scientific tasks of the experiment, the program of measurements on the surface of Mars and described in detail the components of the equipment and the features of their work.

从火星表面探测火星大气的激光雷达

该激光雷达设备是ExoMars-2022着陆平台气象综合体的一部分，旨在研究火星气溶胶、行星边界层和小规模大气湍流。在光子计数模式下，基于脉冲半导体激光器和雪崩光电二极管的微型激光雷达将有可能获得白天10至1500米垂直路径上的气溶胶后向散射曲线，夜间15至10000米垂直路径上的气溶胶后向散射曲线。在被动模式下，天空亮度是在一个狭窄的光谱范围内测量的，在一个狭窄的立体角上，频率高达数百赫兹。测量到的波动可以提供有关白天大气湍流及其与尘埃活动关系的信息。本文考虑了实验的科学任务、火星表面测量方案，并详细介绍了设备的组成和工作特点。

期刊介绍： Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
