Abstract
A self-correcting inductive fuze setter is used to detect and correct any errors that might occur during transmission and reception of a velocity corrected time data word so that a projectile will be detonated at the proper time. The self-correcting inductive fuze setter uses an error detection/correction algorithm to create an encoded data word from the velocity corrected time data word. Next, the encoded data word is used to digitally modulate a carrier signal, which is then transmitted from the muzzle of the weapon to the projectile. The received carrier signal is then demodulated by a demodulator/filter and decoded by a decoder located on the projectile producing the original velocity corrected time data word. In addition, the self-correcting inductive fuze setter will measure the error in both the high-speed fuze oscillator and the low-speed fuze oscillator located on the projectile and adjust the transmitted data word to account for these errors. Lastly, enhanced noise interference rejection is obtained by encasing the muzzle extension in a magnetic metal.
