ABSTRACT:
The apparatus for measuring the muzzle velocity V.sub.0 of a projectile fired from a weapon enables eliminating the effects of interfering magnetic fields, particularly that of the terrestrial magnetic field. For this purpose the apparatus comprises a shielding arrangement for shielding or screening interfering magnetic fields. Such measuring apparatus contains two induction coils and a support for the attachment thereof which is made of a material of low magnetic permeability. For shielding or screening the interfering magnetic fields there is used a shielding arrangement made of a material of high magnetic permeability. The apparatus is simultaneously constructed as a muzzle brake and is suitable for measuring the muzzle velocity of sabot projectiles.
