Abstract
Three algorithms of the Monte Carlo method for calculation of impulse transfer function in channels of laser sensing and communication are considered: the local estimation algorithm, the double local estimation algorithm, and the suggested modified double local estimation algorithm. Results of testing of the algorithms and their comparison are considered. For a homogeneous medium, the complexities of the algorithms are compared, demonstrating under what conditions the suggested algorithm is advantageous as compared to the double local estimation algorithm. The contributions of double, triple, and higher-order scattering are numerically estimated. High contribution of multiple scattering proves the expediency of application of the Monte Carlo method for solving problems of this type.
