基于CEEMDAN‑IWT的冲击波压力信号降噪方法
针对实测爆炸冲击波信号中包含大量噪声信号，对试验结果分析及弹药爆炸毁伤威力评估造成一定影响等问题，提出了一种基于自适应噪声完备经验模态分解（complete ensemble empirical mode decomposition with adaptive noise，简称CEEMDAN）和改进的小波阈值（improved wavelet threshold，简称IWT）的冲击波信号联合降噪方法。首先，将待处理信号通过CEEMDAN进行模态分解，得到系列本征模态分量（intrinsic mode functions，简称IMFs）；其次，对传统的小波阈值方法进行改进，通过计算各分量每层分解...
