Optical design of dual mode seeker for short-wave infra-red and four quadrant detectors in missile application

摘要

In missile applications, countermeasures are one of reasons for enhanced rate of false alarm. Aiming to o decrease falsealarm rate, algorithms are used but it would be useless for some kind of countermeasures. Adding benefits of two or morewavelengths to seeker subsystem makes overall system more robust to countermeasures. In this study, first criticalmissile parameters will be given. Then; proposed short-wave infra-red and four quadrant method will be discussed. Inaddition; two different optical designs have been made for short-wave infra-red imaging and four quadrant systems.Optical designs performances have been illustrated in simulation results. Furthermore, opto-mechanical design of thedual mode seeker is illustrated. Finally, conceptual design of dual mode seeker will be summarised.
