The paper considers the problem of optical radiation propagation in a passive laser reflector satellite orbiting the Earth, along with reflected signal formation at the earth surface. In these conditions, the optical system will be significantly affected by moving media optics, which may interfere with the possibility of receiving the signal reflected by the satellite. The paper aims to develop a mathematical simulation taking into account the effects of moving media optics and track the spatiotemporal structure of the signal as a function of the optical system velocity.
The paper considers the problem of the laser radiation propagation from the Earth surface to a Luneburg lens moving at a speed V along a geosynchronous orbit, and the registration by a ground-based observer of radiation reflected by a lens. Preliminary calculations show that the beams reflected by the moving lens deviate at different angles, which leads to the mixing of the beams on the Earth’s surface in the region of the radiation recorded. That, in turn, affects the appearance of the interference pattern and the process of recording the radiation reflected by the lens. Therefore, the purpose of this work is to calculate the formed optical response in the reception area of the radiation, taking into account the optical effects of the moving media: the Fizeau effect, the Doppler effect, violation of the Snell’s law, the kinematic effect of the beam points displacement on the optical surface caused by the final velocity of radiation in the lens.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
