Abstract

Raman spectra interpretation takes the physical reasons that substantially determining the Raman band broadening, the shift of the spectral lines, their form distortion and difference between the measured intensity of the Raman line and its true value. The lidar Raman spectrum transformation of the gaseous molecules of the methane CH₄, propane C₃H₈ II butane C₄H₁₀ mixture at the number of the ranging laser radiation wavelengths with the distance in a range of 0,1 - 2,0 km have been fulfilled. The designed computer modeling procedure allows to predict a type of the lidar Raman spectrum of a methane, propane and butane mixture at the various ranging distances for the chosen wavelength of the cooper vapor laser and by this way that to increase the concentration measurement accuracy of studied molecules in a gaseous mixture.
