Claim:
1. A method comprising: sensing a shockwave associated with a projectile, in response to the shockwave impinging on a plate, wherein the shockwave results in resonance being generated in the plate, wherein a piezo electric sensor is associated with the plate, wherein the piezo electric sensor senses the shockwave having a first frequency, wherein the sensing of the shockwave is isolated from an effect of an acoustic wave that is in proximity to the plate and has a second frequency, wherein the acoustic wave is associated with at least operational noise of a vehicle, wherein the sensing of the shockwave is isolated from the effect of the acoustic wave to facilitate the sensing of the shockwave associated with the projectile without the sensing of the shockwave being affected by the acoustic wave, and wherein the first frequency is higher than the second frequency; and generating a signal in response to the sensing of the shockwave, wherein the signal is generated by the piezo electric sensor.
