Some parameters of the antenna complex of the station for high–altitude laser sensing of the atmosphere developed at the Institute of Atmospheric Optics of the Siberian Branch of the Russian Academy of Sciences are presented. The antenna complex is a part of a large multipurpose lidar which is currently under development. The main element of complex is a parabolic mirror 2205 mm in diameter. In addition to the main goal of increasing the sensing range the design of the antenna complex is also aimed at providing:
– versatility understood as a possibility of simultaneous application of laser sensing techniques based on recording the signal of elastic scattering at several wavelengths, including differential absorption methods and Raman scattering techniques;
– operation under conditions of high levels of background noise corresponding to light summer nights and to illumination of a city;
– operation under severe climatic conditions of winter.
This paper is devoted to the discussion of starting premises and measures adopted to achieve these goals.
