The Operational Principle Analysis of New Airborne Electro-Optical Targeting System( EOTS) of US Army

The Electro-Optical Targeting System(EOTS) integrates forward-looking infrared(FLIR) and infra-red 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 operat-ing 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 in-troduced. The operational principle and steps of the automatic bore sight calibration system of EOTS are ana -lyzed emphatically .Finally, the performance of EOTS system is summarized .
