Выбор лазеров для увеличения дальности бортовых локационных систем космических аппаратов

Выбор лазеров для увеличения дальности бортовых локационных систем космических аппаратов

Abstract

Цель работы состоит в анализе возможностей и выборе лазерных источников для бортовых лазерных локационных систем (ЛЛС) космических аппаратов (КА), предназначенных для локации по диффузно отраженному сигналу и по уголковым отражателям (УО). Приведены характеристики полупроводниковых, твердотельных и волоконных лазеров. Выполнена энергетическая оценка дальности бортовых ЛЛС в импульсном и непрерывном режиме излучения с использованием лазеров разных типов. Показано, что увеличение дальности ЛЛС по диффузно отраженному сигналу до 10 километров обеспечивается с использованием волоконных лазеров, а для дальности более 10 километров уже необходим переход на твердотельные лазеры. Проведена оценка влияния параметров УО на дальность ЛЛС. Полученные в работе результаты могут использоваться при разработке бортовых ЛЛС для перспективных КА.
