Design of dual mode seeker for millimeter wave and four quadrant detectors in missile application

In missile applications, countermeasures are one of critical aspects to be handled. New technological improvements affect missile performance because of effectiveness of countermeasures. To eliminate countermeasures' effects, different mode seeker will be need. Two or more different modes in seeker increase immunity to different kind of countermeasures. Because of these reasons, two different modes are chosen for seeker design of this work. One of them is millimeter wave and other one is four quadrant. By using this two different seeker concept, weakness of individual system will be eliminated by each other. In this work millimeter wave and four quadrant system range performance will be calculated and optomechanical design will be shown with respect to some sample missile criteria. After that seeker performance of system will be compared with other dual mode seekers.
