ABSTRACT:
A magnetic proximity fuse for initiating a charge of a moving charge carrier. The proximity fuse includes at least one sensor for sensing a terrestrial magnetic field and producing a signal. At least one sensor senses movement of the charge carrier and produces a signal. A signal processor receives signals from the at least one magnetic field sensor and the at least one movement sensor and produces an output signal to initiate the charge of charge carrier only in response to changes in the terrestrial magnetic field caused by ferromagnetic objects other than the charge carrier or movement of the charge carrier, the output signal initiating the charge of the charge carrier.
