Abstract:

The possibilities of remote sensing of chemical warfare agents by the differential absorption method are analyzed. The СО₂ laser emission lines suitable for sensing chemical warfare agents with accounting for disturbing absorption by water vapor were chosen. The detection range of chemical warfare agents is obtained for a lidar based on СО₂ laser. Factors influencing upon the sensing range have been analyzed.
