Abstract:

This study presents a new dual-sensor summation technique for cross-ghosting based on F-K domain, which uses the F-K domain cross-ghosting equations to obtain a calibration factor by matched filter, to optimize the dual-sensor summation technique. Both the synthetic and practical data processing have good results. The ghost is suppressed and the frequency band is broadened. The new method has achieved better results and higher signal-to-noise ratio compared to the traditional methods.

Keywords: dual-sensor summation   cross-ghosting   F-K domain   matched filter
