Abstract:

The lidar equation is obtained for Raman backscattering of light by hydrogen molecules in the atmosphere, taking into account the finite width of the laser line. The characteristics of the lidar signal of Raman scattering of light by hydrogen molecules in the atmosphere are investigated, taking into account the finite width of the laser line. The lidar signal is numerically modeled, and it is shown that the time to measure the Raman scattering signal by hydrogen molecules of a specified concentration can be shortened by about an order of magnitude, while the width of the lidar spread function is increased by an order of magnitude.
