Распространение ÑÐ»ÐµÐºÑ‚Ñ€Ð¾Ð¼Ð°Ð³Ð½Ð¸Ñ‚Ð½Ñ‹Ñ Ð²Ð¾Ð»Ð½ в лесном массиве

Abstract

Ð’ работе представлен теоретический Ð¿Ð¾Ð´Ñ Ð¾Ð´ для решения задачи при Ð¿Ñ€Ð¾Ñ Ð¾Ð¶Ð´ÐµÐ½Ð¸Ð¸ ÑÐ»ÐµÐºÑ‚Ñ€Ð¾Ð¼Ð°Ð³Ð½Ð¸Ñ‚Ð½Ñ‹Ñ Ð²Ð¾Ð»Ð½ сквозь лесной массив. Рассмотрено и рассчитано влияние одного дерева на Ð·Ð°Ñ‚ÑƒÑ Ð°Ð½Ð¸Ðµ электромагнитной волны. Представлены расчеты, позволяющие найти постоянную Ð·Ð°Ñ‚ÑƒÑ Ð°Ð½Ð¸Ñ и рассеяния, также выведена и доказана оптическая теорема для двумерного варианта задачи. Проведенный анализ Ð¸Ð¼ÐµÑŽÑ‰Ð¸Ñ ÑÑ Ð´Ð°Ð½Ð½Ñ‹Ñ Ð¿Ð¾ÐºÐ°Ð·Ð°Ð», что обобщенной теории, объясняющей природу и влияние лесного покрова на Ð·Ð°Ñ‚ÑƒÑ Ð°Ð½Ð¸Ðµ передаваемого радиосигнала, до ÑÐ¸Ñ Ð¿Ð¾Ñ€ не было сформулировано. Полученные теоретические соотношения для одного дерева и для лесного массива Ñ‚Ð¾Ð½ÐºÐ¸Ñ Ð´ÐµÑ€ÐµÐ²ÑŒÐµÐ² (по сравнению с длинной волны) промоделированы на Ð³Ñ€Ð°Ñ„Ð¸ÐºÐ°Ñ . Учтено взаимное влияние деревьев друг на друга Ñ‚.е. возникающие переотражения между ними.
