Цель работы: оптимизация работы FSO системы распределенного типа, где центральный передающий центр посылает оптические сигналы на n количество приемников, удаленных от центрального пункта на разные расстояния.
Метод: Введено на рассмотрение оптимизационная функция в виде функциональной зависимости между интенсивностью дождей (R) и дистанции до оптических приемников l. Составлен целевой функционал содержащий оптимизационную функцию и характеризующий суммарное ослабления оптического сигнала по всем каналам. Сформулирована и решена оптимизационная задача вычисления оптимального вида указанной функции при котором суммарное ослабления оптического сигнала достигает минимальной величины.
Результаты исследования: решена оптимизационная задача, которое показало, что при наличии обратной логарифмической зависимости l от R суммарное ослабление в распределенной FSO системе достигает минимальной величины.
Научная новизна: впервые решена задача оптимального учета влияния дождей на эффективность работы FSO систем распределенного типа, с учетом ослабления используемого лазерного луча при наложении ограничения на суммарную протяженность дистанций до приемников.
The purpose of the work is to optimize the operation of the FSO system of a distributed type, where the central transmitting center sends optical signals to the number of receivers remote from the central point at different distances. n
Method: An optimization function in the form of a functional dependence between the intensity of rain and the distance to optical receivers has been introduced. A target functional containing an optimization function and characterizing the total attenuation of the optical signal on all channels has been compiled.
Results of the study: the optimization problem was solved, which showed that in the presence of an inverse logarithmic dependence on the total attenuation in a distributed FSO system reaches a minimum value.
Scientific novelty: for the first time, the problem of optimal consideration of the impact of rain on the efficiency of FSO systems of distributed type is solved, taking into account the attenuation of the laser beam used when imposing a limit on the total length of distances to receivers.
