I have a vibroseis dataset which has been collected in the field. To my knowledge, the recorded signal s'[t] is the convolution of the original sweep s[t] and the reflection response r[t] of the layered earth. Thus, the relationship is expressed in its simplest form as s'[t] = s[t]*r[t], neglecting the effects of earth attenuation and noise. However, I do not have the reference sweep s[t] since this data has been transferred from tape, and unfortunately, the tape has been damaged and discarded sometime in the past. (I do not even have the original media on which the signal was recorded). All that I have is s'[t]. Is there a way to recover the reflection response r[t] without use of the original reference sweep s[t]?
vibroseis deconvolution without the reference sweep

This is a mistake. Please disregard. I had submitted the same post earlier, but I thought that this one did not make it due to a server error. Apparently it has found its way on comp.dsp about a day later. You can see the original post above by searching this archive for "vibroseis deconvolution without the target sweep." My apologies for any inconvenience that this may have caused. Nicholas (namespace)>I have a vibroseis dataset which has been collected in the field.
