PURPOSE:To simplify the constitution of an automatic tracking system by detecting the angular speed of an airframe and an error angle from the visual-line direction of a target, and allowing an electric seeker shaft to scan by a control signal obtained from the angular speed and error angle. CONSTITUTION:The error angle vector epsilon between a target line unit vector T indicating the direction of the target and a unit vector S indicating the direction of the electric seeker shaft is detected by an error angle detector 1 and amplified by an amplifier 2 with a gain K1. The output of the amplifier 2 and the output of a rate detector 3 which detects the angular speed omega of the airframe to the inertial space are used by an electric seeker shaft scan control part 4 to allow the electric seeker shaft to follow up the target regardless of the oscillation of the airframe. The output of the amplifier 2, on the other hand, is used by the steering controller 6 consisting of a steering device 5 and the detector 3 to swivel the airframe, which is then guided so that the error angle epsilon is zero. An electric seeker shaft control signal is obtained from the Coriolis expression by using the error angle epsilon and angular speed omega. |
