| Abstract: | It is vital to eliminate random noise in processing seismic data with low signal--to--noise ratio. The data with low signal--to--noise ratio of Jianghan Region are processed by means of mid--value filtering technique including removing noise by vector resolution under the control of multilevel mid--value filtering and mid--value on the basis of directional signal measurement. The results show that random noise is suppressed effectively, and that signal -- to-- noise ratio is obviously increased. |
