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.
