The imitative model of dispersion of the laser radiation is developed, allowing to define statistical characteristics of value of intensity of the absent-minded radiation arriving on an input of the prospecting receiver, for various states of atmosphere. The model is based on representation of the dispersing environment in the elementary volumes containing casual value of concentration of particles (N), submitting to the law of the Poisson. In turn the sizes of particles ri represent random variables which submit to the continuous law of allocation. In the course of simulation modeling depending on concentration of particles N in the elementary volume and according to the law of allocation of number of particles in the sizes a row of values of the sizes of particles according to which values of coefficients of dispersion and indicatrix of dispersion of each of particles are defined is formed. In the assumption that the radiation dispersed from everyone particle is additive among themselves and background (interfering) radiation, adding the received values of coefficients of dispersion and indicatrix of dispersion of particles, considering the sizes of the elementary volume, we receive value of volume coefficient of dispersion and indicatrix of dispersion of this volume. The values of volume coefficient of dispersion received as a result of simulation modeling and dispersion indicatrix are included into the equation of calculation of intensity of the absent-minded radiation arriving on an input of the prospecting receiver. The coordination received statistical and theoretical allocations with criterion usage «χ2» Pirsona is led.
