Monte Carlo Simulation of Polarized Signals of a Laser Navigation System

Algorithms for stochastic simulation of a polarized signal arriving at a photodetector of an aircraft laser navigation system are developed. The angular distributions of Stokes parameters of radiation recorded by the detector are estimated by a Monte Carlo method; the effect of different-order scattering on the total recorded signal and polarization degree is analyzed. The signal intensity is calculated with the use of linear polarization filters. The suggested algorithms enable estimating the efficiency of the laser navigation system taking into account radiation polarization under different weather conditions and a possibility of enhancing signal contrast by using the polarization filters.

期刊介绍： Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
