摘要
建立了一套完善的冲击波测试系统,完成了对爆炸冲击波的测试实验,并运用小波分析对测试结果进行了处理。为了有效分离杂波对爆炸冲击波测试信号的干扰,在比较不同常规信号处理方法的基础上,提出了一种基于小波变换的爆炸冲击波实测信号处理方法,对冲击波信号的分析处理有很好的可操作性和实用性。结果表明,所采用的测试方法合理可靠,所采用的小波处理方法能够准确判断信号的间断点,分离出噪声干扰,获取不同频段的能量值。
A perfect shock wave measurement and test system was established,the experiment of shock wave test was finished and the results were analyzed by using wavelet. In order to separate the effect of clutter interference from the test of shock wave,different signal processing methods were compared,and wavelet transform based signal processing method was proposed. This method is feasible and practical. The results show that the system is reasonable and reliable. The wavelet processing accurately judges signal discontinuities,separates signal noise and achieves energy of different bands.
