Seeker for guided missile has electro-optical seeker mounted in Cardan frame with actuators to align seeker onto target

摘要

The seeker for a guided missile has a Cardan frame (18,22) carrying an electro-optical seeker (16) assembly which aligns on a target beam. Actuators (36,38) align the seeker assembly onto the target. The seeker assembly has a single roll axis (42) and a perpendicular pitch axis (20) to support it in the missile airframe. The rotational angle of the seeker is read by a monitor (28) and an inertial sensor (48) measures the angular velocity around the three perpendicular axes.
