摘要
采用匹配滤波器来消除浅海水下冲击声源多次脉动对测量的影响。其结果具有节省内存,计算速度快的优点,与维纳滤波一样。还对比研究了去卷积滤波和预测维纳滤波两种方法。指出在浅海水域,这两种方法的效果均不理想。
We propose the matched filter approach for the removal of bubble oscillations from marine seismograms The matched filter works as well as the Wiener filter We study also two other approaches: the deconvolution filter and the predictive Wiener filter. The results show that the debbubling effects of these two approaches arc not satisfactory for marine seismograms in shallow water.
