PROBLEM TO BE SOLVED: To maintain stability of a flight route by suppressing noise generated in a seeker at each flying point over the entire flight route.SOLUTION: A missile guidance system includes a seeker part for performing tracking looping based on a gimbals command signal magnifying an error angle with a fixed value, an error angle processing part for calculating the change rate of an error angle based on the error angle, a spatial angle calculation part for calculating a target spatial angle and a target spatial angle speed based on the error angle, the gimbals angle speed command signal, and the change rate of the error angle. The spatial angle calculation part calculates a calculatory error angle based on a difference between the integrated value of target spatial angle speeds and the integrated value of gimbals angle speed command signals, calculates a target spatial angle speed based on a difference between the error angle output from the seeker part and the calculatory error angle, calculates an error angle change amount based on a difference between the gimbals angle speed command signal and the target spatial angle speed, corrects the target spatial angle speed by using a difference between the change rate of the error angle and the error angle change amount, and guides the missile to a target based on the target spatial angle speed and the target spatial angle. |
