GUIDING METHOD OF MISSILE

摘要

PURPOSE:To improve a sensing accuracy for a target position and an accuracy of an on-target impart by a method wherein a reflecting sound of a sound wave reflected from a target object from an active soner is caught by a sono- buoy and a position of a target object is calculated in response to a transmitting signal and then a missile is guided. CONSTITUTION:Active soner 23 on a marine 1 disperses sono-buoys 13, transmits a sound wave 25 to a target object 20. Its reflecting sound 26 is caught by each of sono-buoys 13. Each of the sono-buoys 13 performs a predetermined calculation and transmits a time information S3 receiving a reflecting sound 26 and a position information S4 of each of the sono-buoys 13 itself. The signal is taken into a missile injecting control device 4 on the marine 1 and a predetermined calculation is carried out, a position of the target object 20 is calculated and outputted to a guiding control part for the missile 2 and then the missile 2 is injected. As the missile 2 approaches the target 20, a torpedo 8 is released below a sea water and for example it starts an activity for the torpedo 8 toward the target object 20 through a homing guide or the like and then if the target object 20 is within an effective range, the missile breaks the target 20.
