Abstract

PROBLEM TO BE SOLVED: To provide a system capable of guiding a certain missile to only one target of a plurality of targets in contrast with conventional guiding systems wherein a plurality of targets are randomly selected and targeted based on random numbers generated in the system, permitting a plurality of missiles to be guided to an identical target simultaneously. SOLUTION: Data on targets and data on a guidance assigned target are transferred from a ground-position radar unit or airplane-position radar unit to the guiding system. Thereafter, this data on targets and the data obtained by the guiding apparatus are matched, so that the data on an assigned target may be selected for guiding only one missile, preventing a plurality of missiles from being guided to an identical target simultaneously.
