| Popis: |
Summary Slip sweep recording offers the potential to dramatically improve vibroseis production rates and to reduce acquisition costs. However, slip sweep data is contaminated by harmonic noise, because one vibrator begins sweeping before the previous sweep has terminated. We present a new method for eliminating harmonic distortion in slip sweep data. The method is derived using only the recorded ground force and the start times for the sweeps. It is simple, robust, and fast and can be easily implemented. It has been applied to synthetic and real data and gives satisfactory practical results. |
