AWD eliminates or attenuates the receiver and/or source ghost in marine acquisition.

It fills the ghost notch and broadens the spectrum. The deghosted signal has a narrow wavelet and provides a broad band and clean image. AWD separates the input data into user-defined windows and searches the best deghost operator in each window. Thus it is data driven and adaptive. The ghost operator is time and spatially variant, and realized in the frequency domain. This adaptive nature allows it to compensate mild 3D effects and uncertainties in water velocity and streamer depth, which other 2D deghosting methods cannot handle correctly. This method has proven robust and stable using both synthetic data and real data, and has also been applied for both wide azimuth (WAZ) and narrow azimuth (NAZ) data.
