Abstract: To measure the shock wave overpressure and the impulse more accurate when the ammunition exploded, a feasible way to measure the shock wave overpressure indirectly was proposed by analyzing the means and features of existing shock wave overpressure measurement. On the foundation of getting the speed, utilized the Rankine-Hugoniot equation to solve the shock wave over pressure, then compared the pressure with which was measured by transducer, to prove the feasibility of this kind of experiment.
