摘要： An apparatus and method for identifying the path/time relationships of a projectile within a weapon barrel, even upon live firing, includes a coupling element having at least two openings in a sidewall thereof through which a generated electromagnetic wave is divided and then introduced into the barrel. The divided wave includes wave parts that propagate toward and away from the barrel, the parts propagating toward the barrel adding up and being introduced into the barrel while the parts propagating away from the barrel cancel each other out. The wave reflects off from the projectile and is then received after undergoing an inverse division.

摘要： For calculating motional characteristics, particularly of a projectile moving in a barrel of weapon, a microwave directed onto the projectile by a measuring structure is superimposed with the reflected wave and a a calculation of location-dependent velocity and acceleration is carried out based on the chronological curve of the phase difference by a one-time or, respectively, two-time differentiation. In order to reduce measured errors, the operating phase difference and, therefore, the location of the projectile is first assigned to each amplitude value in a registered interferometer signal. A compensation function for the time-dependent location of the projectile is then placed through the arc-cosine-transformed individual action points and the location-dependent projectile velocity is calculated by one-time differentiation and the acceleration is calculated by a further differentiation.
