| 摘要 |
The invention relates to a waveguide arrangement (1) for measuring the speed of a projectile (2) during passage through a weapon barrel arrangement, wherein a main waveguide (4) and at least one auxiliary waveguide (5) are provided, wherein the main waveguide (4) has a cross-section suitable for the passage of the projectile (2), wherein the auxiliary waveguide (5) extends adjacent to the main waveguide (4) and is connected to the main waveguide (4) via an opening (6), and wherein an isolator (11) is arranged in the auxiliary waveguide (5). An improved waveguide arrangement (1), in particular for large-calibre ordinance, is provided such that the at least one coupler (8, 9) extends at least partially in the isolator (11), wherein the speed of the projectile (2) located in the main waveguide (4) can be measured at a frequency below the limiting frequency, and wherein the transmitting coupler (9) is arranged at a distance to a muzzle of the weapon barrel arrangement, in order to prevent an exit of the generated signal from the weapon barrel arrangement. |
