Version française AT-01, Acoustic Trigger Device
A
trigger device is required if the radar data acquisition needs to be
synchronized with an external event such as the projectile exiting the
muzzle. An acoustic transducer can be used to achieve this goal.
The acoustic trigger device is generally located very close to the
muzzle. It is very rugged and can sustain the blast and shock of large
caliber guns.
A simple 50 Ohm coaxial cable is required.
