<p>PROBLEM TO BE SOLVED: To prevent the conical scans of a gimbal during tracking of a target from affecting a guidance signal output to a flying object. SOLUTION: If a command 14 for conical scans is added just before the addition point of angular velocity feedback during tracking of a target, the sum of the command 14 for the conical scans and a guidance signal 6 becomes an input to a gimbal control part 1 and a gimbal is conically scanned with a tracked target position as the center. A signal indicating the distance traveled by the gimbal is generated in the guidance signal 6. If the command 14 for the conical scans is input to a canceling element 15 imitating the response of the gimbal and computations are performed, a signal that is the same as an output obtained when the command 14 for the conical scans is input to a track loop block is obtained in that output of the canceling element 15. Therefore, the output of the canceling element 15 is subtracted from that output immediately after a track gain 5 on a track loop, whereby the signal component generated by the command 14 for the conical scans can be canceled out from the guidance signal 6.</p> |
