Прикладные вопросы разработки бортовой лазерной локационной аппаратуры

Прикладные вопросы разработки бортовой лазерной локационной аппаратуры

Abstract

В работе обсуждаются вопросы реализации бортовых лазерных локационных систем (ЛЛС) для космических аппаратов (КА). Рассмотрено применение разных типов лазерных источников и фотодетекторов, а также электромеханического оптического аттенюатора. Описаны конструктивные решения, используемые для компенсации снижения чувствительности фотоприемного устройства. Показаны преимущества использования волоконных лазеров при измерении скорости сближения КА и при сканировании больших полей обзора. Определена зависимость ослабления оптического аттенюатора от дальности измерений, обеспечивающего защиту фотоприемного устройства при наличии близкорасположенных диффузно отражающего пассивного КА и уголкового отражателя. Выполнена оценка надежности бортовой ЛЛС в зависимости от наличия в составе аппаратуры электромеханического оптического аттенюатора
