Muzzle velocity measuring apparatus and method
The present invention relates to an apparatus for measuring a muzzle velocity of a fired bullet so that the bullet may explode at an accurate location. The muzzle velocity measuring apparatus includes a detector configured to comprise a pair of cores encircled by probe wound coils and installed in two separate positions in an adapter, and to output a muzzle velocity signal based on eddy current signals which are generated by the probe wound coils when a bullet fired from a bullet chamber passes through the adapter, a muzzle velocity calculator configured to calculate a flight speed of the fired bullet based on the muzzle velocity signal; and a transmitter configured to transmit the calculated flight speed to the bullet..
