WebSince the CMP gather is the time–domain data, the source wavelet is transformed into the frequency domain to apply full Newton method. Finally, it is transformed back into the time domain. Through numerical examples, we show how sensitive the source wavelet inversion is to both the direct waves on CMP gathers and the uncertainty of initial ...

Webreceiver location. The number of traces in a CMP gather is the fold. The distance between source and receiver is the offset. Geophysicists make moveout corrections to shift all traces so that reflec - tions in a CMP gather appear horizontal at their zero-offset times. Then, in a process called stacking, they add together the traces in the CMP ... WebWhether it's raining, snowing, sleeting, or hailing, our live precipitation map can help you prepare and stay dry.
