In order to study measurement methods of week pressure signal
small-dose underwater explosion experiments are conducted in pool to validate the feasibility of PVDF sensor with enlargement circuit in it. Test result shows that consistent waveform curves of shockwave and bubble pulsating pressure are obtained in 5 g TNT underwater explosion in pool. PVDF sensors have the advantages of high frequency response
high sensitivity
simple fabrication and low cost
and can be used to test week pressure signal in underwater explosion.
