A system and method of processing seismic signals wherein seismic data resulting from a reflected seismic wave is received at a multi-component receiver. A mask trace is generated as a function of the seismic data received at the multi-component receiver, and a single type of seismic signals from the seismic data received at the multi-component receiver is identified and extracted utilizing the mask trace. Generating the mask trace further includes multiplying the seismic data received at two of the components of the multi-component receiver to produce a first result. A positive/negative sign of the first result is identified to produce a first binary result. The first binary result is divided by a scaling factor to produce the mask trace. Extracting the single type of seismic signals further includes multiplying the seismic data received at one component of the multicomponent receiver with the mask trace wherein the single type of seismic signals represents seismic waves received at the one component of the multi-component receiver. In another embodiment of the present invention, generating the mask trace further includes multiplying the seismic data received at two different components of the multi-component receiver to produce a second result. A positive/negative sign of the second result is identified to produce a second binary result. The second binary result is multiplied with the first binary result and then divided by a scaling factor to produce the mask trace. |
