Optical design of dual-mode seeker for long-wave infrared and four quadrant seeker in missile application

摘要

Warfare environment get more complex day by days by developing technology. This improvements and complexity cause missile performance degradation. To eliminate these negative aspects, more technological and more complex systems and algorithm are used in new generation missile. Dual mode or triple mode seekers are produced to resolve these problems. More effective and more reliable system can be achievable by combination of different kind of working principle. In this study, cost effective imaging and signal processing solution combination is reviewed. Its conceptual design criteria are assumed in system level and both designs of systems are illustrated. In imaging part, uncooled long wave infrared is chosen for both cost effective and compactness. In signal processing part, four quadrant semi-active seeker is chosen for same reason. Finally, their performance results are shown.
