System Design of An Infrared Dual-band Seeker

Abstract

Infrared imagine seeker is an important development direction of ground-to-groung ballistic missle terminal guidance technology, but it's derection probability is vulnerable to target/background characteristic detector performance field of view and other factors. In order to improve the ability of infrared seeker to adapt to complex battlefield environment, a new design principle of infrared dual-band seeker is introduced. The whole system adopts dual band design, and uses image fusion technology to enrich the information difference between target and background features. In addition, the design of large and small dual field of view can further improve the target interception and accurate recognition and tracking ability of seeker. The working principle of infrared seeker is analyzed, and the optical design idea and image fusion method are introduced. Through index analysis and calculation, the infrared seeker meets the system requirements, which can provide reference for future ballistic missle seeker design.
