Main Trends in the Improvement of Software of Mobile Laser Remote Chemical Reconnaissance Complexes

Abstract

The contemporary level of the development of the theory of laser location and technical possibilities of lidar systems allows not only to solve certain problems of remote control of the optical properties of aerosol formations, but also to measure their concentrational characteristics and the parameters of the distribution function of the aerosol particles, using multi-frequency laser sensing. Because of that the remote means of chemical reconnaissance of active type with the function of measuring the parameters of aerosols of toxic substances and highly active toxic substances represent a new generation of such technologies. It is possible to give certain promising mobile lidar complexes of remote chemical reconnaissance special functions of measuring systems by introducing modern software and special algorithms for reversing lidar sensing data into macro- and microstructural characteristics of clouds of physiologically active substances (PhAS) in the atmosphere. This ensures control of the concentrations of multicomponental mixtures of PhAS, the parameters of the distribution function of the aerosol of PhAS by dispersion with the overlapping of isolines of the concentrations of the displayed PhAS on the terrain map. Mathematical studies allows us to formulate basic requirements for multi-frequency lidar measurements – optical measurement error for all λi should not exceed 5% - the imaginary part of the complex index of refraction of the substance of the aerosol of PhAS should be χ ≤ 0, 005 the error in specifying the real part of the complex refractive index must be within +_0,02. If these requirements are met, this sensing method becomes an effective tool for the study of the disperse composition of aerosols
