Testing method for overpressure of shock wave form underwater explosion

According to the principle of shock wave propagation in the medium, we obtained a calculation method for overpressure of shock wave in the medium. By applying land vibration testing sensor to underwater vibration testing, the vibration velocity of particle is detected and then turned into overpressure. By using the principle of the least square, a calculation formula for shock wave overpressure of the far underwater explosion is worked out. This work is significant for guiding the future actual testing work and reducing the testing workload and decreasing the cost.
