AAI's Projectile Detection and
Cueing (PDCue) system uses a tetrahedral array, or conformal
microphones distributed at the four corners of the vehicle.
The conformal system assembly is more expensive but provides
better accuracy and redundancy and is better suited for remote
weapon station application. The system displays a situational
map on a console, depicting the vehicle and relative location
of the sources of fire identified. The system can operate on
moving or stationary vehicles.
