【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。更多还原

【Abstract】 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.更多还原
