Abstract

One of the main evaluation methods of damage effectiveness for weapon system is gathering muzzle shock wave signals through an overpressure test system of shock waves at first, then processing and analyzing acquired data. The evaluation performance depends on the appropriateness of signal processing. This paper proposes a method based on the multi-resolution characteristics of wavelet analysis to denoise the muzzle shock wave signal aimed at the characteristics of wide frequency band, sudden change and short duration of the shock wave signal, which not only filters the impurity signal effectively, but also reduces time delay. Then, according to the different locations of the sensors, overpressure peaks of every de-noising signal are obtained. The shock wave field is modeled by the interpolation methods with those overpressure peaks data. Finally, errors analysis of shock wave field model has been accomplished.
