METHOD FOR GUIDING AND CONTROLLING SIDE THRUSTING TYPE MISSILE

摘要

PROBLEM TO BE SOLVED: To enable a guiding performance to be improved by a method wherein a non-sensitive band width of a non-sensitive band relay in a guiding loop for a side thrusting type missile is scheduled in a relative distance between it and a target. ;SOLUTION: In a guiding loop 4 for a side thrusting type missile, a non-sensitive band width D of a non-sensitive band relay 5 is increased at an initial time of guidance for a side thrusting type missile showing a long relative distance R in respect to a target. Then, as the relative distance R between the missile and the target is decreased, the non-sensitive band width D of the non-sensitive band relay 5 is gradually decreased. With such an arrangement as above, a small-sized rocket motor having an equivalent high thrusting force far spaced apart from a position of center of gravity of the missile is at first ignited to roughly guide the missile in a wide range, thereafter a small-sized rocket motor of which equivalent thrusting force is gradually decreased as it is gradually approached to the position of the center of gravity of the missile is ignited so as to guide the missile to approach the target and then it is controlled such that an erroneous angle between the missile and the target may become zero.;COPYRIGHT: (C)1997,JPO
