Abstract
An actual problem today is the improvement of a mobile optical reconnaissance system designed to detect snipers, observers, artillery correctors, including camouflaged ones equipped with optical sights. With the help of optical surveillance devices, it is possible to detect and estimate the distance to them, the principle of operation of which is based on the use of the physical effect of light reflection, which consists in the ability of optical systems to reflect probing radiation in the reverse direction at an angle close to the angle of its incidence, that is, illumination by a laser and capture of the reflected image, as well as the processing of this signal. The study of the processes of the propagation of laser radiation in the atmosphere (including in a turbulent environment) is given considerable attention in connection with the wide application of lasers in systems operating through the atmosphere. Indeed, the accuracy of laser devices of a wide range of applications (geodetic, in weapons systems and military equipment, portable, mounted in the system of combat equipment of a serviceman performing special tasks, etc.), spatial and temporal separation of laser locators, the possibility and accuracy of determining environmental parameters by remote laser methods can be estimated only taking into account the fluctuations of the field of optical beams.
