Resumen
The application of an imaging condition in wave equation shot profile migration is important to provide illumination compensation and amplitude recovery. Particularly for true-amplitude wave-equation migration algorithms, a stable imaging condition is essential to successfully recover the medium reflectivity. We study a set of image conditions with illumination compensation. The imaging conditions are evaluated by the quality of the output amplitudes and the artifacts produced. In numerical experiments using a vertically inhomogeneous velocity model, the most stable of the tested imaging condition divides the up- and downgoing wavefields after inverse Fourier transform. 5
