Постановка проблемы. Аналоговые оптические тракты (АОТ) находят широкое применение в современных радиотехнических задачах. Основная функция АОТ – транспорт сверхвысокочастотных аналоговых сигналов. Современные задачи обработки сигналов предъявляют высокие требования к их информативности, где важной проблемой является определение наилучшего компромисса между отношением сигнал/шум и свободным динамическим диапазоном, обеспечиваемым в АОТ. Под линеаризацией АОТ понимаются те или иные действия, обеспечивающие повышение свободного динамического диапазона с целью уменьшения нежелательных искажений сигнала.

Цель. Исследовать методы линеаризации АОТ с внешней модуляцией.

Результаты. Проанализированы современные методы линеаризации сверхвысокочастотных аналоговых оптических трактов.  Выделены основные группы методов: электронные, оптические и гибридные. Рассмотрены основные тенденции и представлены достигнутые результаты по повышению свободного динамического диапазона аналоговых оптических трактов.  Практическая значимость. Рассмотренные методы позволяют существенно повысить информативность сигналов сверхвысокочастотных аналоговых трактов.
