A Fourier integral algorithm and its GPU/CPU collaborative implementation for one-way wave equation migration

► We present a new OWE migration method called the Fourier integral method. ► It uses the exact form of the extrapolation operator without any approximation. ► We use extrapolation matrix to analyze the stability condition of the method. ► We use GPU acceleration to make it faster than other CPU based OWE methods. ► The imaging accuracy is better than those of most other OWE methods.
