Abstract: The development of shipborne helicopter abroad was summarized. The tactics function and campaign mission of optoelectronic system in the helicopter campaign concept of United States navy were discussed in detail. According to multiple spectrum targeting system, which will be the main EO system of U.S. shipborne helicopter, the technologies status and development trend were analyzed according to the sensors, filed of views, image processing and cooperative combat.The sensor resolution reached 1 280 pixel720 pixel, the biggest field of view (FOV) was bigger than 40while the smallest FOV was smaller than 1. The common path and two-level stabilization technique were used to improve the stabilization accuracy to less than 5 rad. Image enhancement, fusion and mosaic should be provided simultaneously and the image delay was smaller than 1 Hz. The inertial measurement unit (IMU) should be integrated to improve the orientation accuracy to 5 m for the target away from 80 km. The development emphases of EO system for shipborne helicopter were also proposed.
