摘要
根据对舰船地震波相关性质的研究,为准确识别舰船地震波,提出基于无限冲激响应滤波器组(IIR)构造具有舰船地震波波形特征的Butterworth小波。通过单轴振动传感器进行地震波数据采集,利用构造的Butterworth小波对所采集数据进行滤波处理,结果证明所构造的Butterworth小波可准确识别舰船地震波。
In order to identify the seismic wave of shallow sea ships accurately,this paper proposes a Butterworth wavelet with the characteristics of ship seismic wave waveform based on the infinite impulse response filter bank(IIR).The seismic wave data are collected by the uniaxial vibration sensor,and the collected data are processed by the constructed Butterworth wavelet.It is proved that the constructed Butterworth wavelet can identify the ship seismic wave accurately.
