The subject of this study is the design of an imaging infrared seeker for aerial targets. Firstly the radiant power of the target was discussed and optical design of seeker lenses were done with ZEMAX Optical Design Software considering the MTF (Modulation Transfer Function) values, optical path ifferences, distortions and detection range calculations. After that, detection range calculations and simulation results of the optical system were presented. Before lock on range calculations, spectral band of the system was analyzed and chosen for aerial targets. After that, lock on range was calculated considering detector noise, background noise and target radiation. Afterward the optical parameters of the seeker were determined. Focal length and F# (F-number) of the seeker was calculated as it was receiving the aerial target and background radiation at 5 km distance. Design was done using ZEMAX optical design program. Moreover, the lens materials were Silicon, Germanium and Cadmium Selenide and Sapphire were dome material. Finally, optical performance parameters have been analyzed. Finally, test plate fitting is applied to the optical system. Manufacturing parameters were presented and discussed.M.S. - Master of Scienc
