美军新型机载光电瞄准系统工作原理分析

The operational principle analysis of new airborne Electro-Optical Targeting System(EOTS) of US army

光电瞄准系统(EOTS)将前视红外和红外搜索跟踪进行了综合,进而可以获得高分辨率图像,实现自动跟踪、红外搜索跟踪、激光指示、激光测距和激光点跟踪。本文针对美国研制的EOTS的工作原理展开分析和研究,概述了EOTS的概念和技术特点,显示了其作为新一代机载光电瞄准系统的先进性。对EOTS多功能系统、光学元件、红外搜索跟踪、维护和研制规划进行了介绍,着重分析了EOTS的自动视轴校准系统,主要包括自动视轴校准系统的工作原理和工作步骤。最后,本文对EOTS系统的性能进行了总结。

The Electro-Optical Targeting System(EOTS) integrates forward-looking infrared(FLIR) and infrared search and track(IRST) to obtain high-resolution images for automatic tracking,infrared search tracking,laser target designating,laser ranging,and laser spot tracking.In this paper,we analyze and study the operating principle of EOTS developed in the United States.Firstly,we summarize the concept and the technical characteristics of EOTS,and present its advanced nature as a new generation of airborne EOTS.Secondly,the EOTS multi-function system,optical components,IR search,maintenance and development planning are introduced.The operational principle and steps of the automatic bore sight calibration system of EOTS are analyzed emphatically.Finally,the performance of EOTS system is summarized.
