A signal enhancement technique for single channel seismic reflection data.
Single channel seismic reflection pro filings have been one of the most popular methods in hydrographic surveys and other geophysical investigations around Japan for the last 20 years. In the shallow water environment, such as continental shelves and continental margins, large amplitude multiple reflections obscure smaller-amplitude primary reflections, which prevent investigators from detecting both fine scale and more important geological structures in that area. To detect more detailed geological information, a digital data processing method using the Wiener shaping filter and conventional stacking was developed to remove noises and multiple reflections from the original data. This method was applied to the digital single channel seismic data obtained at sea near Tokyo Bay, and results of the processing are given in the form of sub-bottom profiles drawn with an automatic plotter and compared with original analogue record seismograms. We can conclude that this method will be of much help in extraction of geological / geophysical information from single channel seismic data.
