The first was using a radar (the average velocity
of the projectile is assumed by the values of muzzle
velocity and velocity of terminal flight phase of the
bullet behind the tested plate), The second method of
velocity measurements used an optical sensor placed
in the terminal phase of the flight path (position of
the sensor was 2 meters from test plate). The weapon
used for the test was a M82 weapon gun, ranged on
the distance of 30 m.
