Abstract
The possibilities of using molecular scattering to determine the wind speed from measurements with a pulsed coherent Doppler lidar (PCDL) from an aircraft at altitudes from 10 to 20 km are numerically studied. The simulation was carried out for sounding radiation at wavelengths of 1 and 2 μm focused at 500 m, the aperture diameter of the receiving-transmitting telescope was set equal to 10 cm. It is shown that the threshold SNR in measurements from an aircraft is attained at pulse energy much lower than when sounding from the Earth. Modern PCDLs with sounding pulse energies of 1–4 mJ, after adding a molecular scattering recording channel, can be used for airborne wind measurements at altitudes of 10–20 km.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
