PURPOSE:To reduce the dynamic range of an integrator, by integrating the difference between the output of an angle error detector and an airframe rate obtained by an external reference gyro and applying the difference between this integrated signal and the output of an angle detector to a gimbals torquing mechanism. CONSTITUTION:A detector 3 for the error angle between an eye angle 1 indicating the direction of a target and a seeker axis 2 which tracks automatically the target is placed on a gimbals having two degrees of freedom. The difference between the output of the detector 3 and an airframe rate 10 for inertia space obtained by an external reference gyro 9 is integrated by an integrator 4, and the difference signal between the output of the integrator 4 and an angle detector 6 which detects the gimbals angle of a seeker is applied to gimbals torquing mechanism 5 to allow the seeker to track the target automatically. The output of the detector 3 is proportional to the eye angular speed of the target, and the difference signal between this signal and the airframe rate 10 for inertia space obtained by the gyro 9 becomes a signal having a small dynamic range. This signal is inputted to the integractor 4 to reduce the dynamic range of the integrator 4. |
