| 摘要 |
The invention relates to a passive magnetic proximity fuse for initiating charging in a charge carrier (1), for example a guided missile, projectile, grenade or the like, when this passes at a certain distance from a ferromagnetic object. The proximity fuse includes one or more sensors (4) for sensing deviations in the terrestrial magnetic field and one or more position-sensing elements (6) (gyros or accelerometers) for sensing the charge carrier's own movement. The signal processor (5) is arranged to emit an active output signal (iout) in association with a deviation in the terrestrial magnetic field such that the active output signal only occurs in dependence on deviations in the terrestrial magnetic field which are occasioned by ferromagnetic objects (3). <IMAGE> |
