Abstract
A piezoelectric sensor arrangement for use in a projectile comprises a piezoelectric sensor enveloped by a damping layer adapted to attenuate signals of frequencies above a predetermined cutoff frequency whereby the voltage output signal of the piezoelectric sensor upon impact on a desired hard target can be discriminated from voltage output signals originating from impact on undesired soft objects. A method of discriminating voltage outlet signals by means of the piezoelectric sensor arrangement and the use of a piezoelectric sensor arrangement in a projectile to safeguard unintentional detonation does not occur is described herein.
