Summary: Many processes in seismic data analysis and imaging can be identified with solution operators of evolution equations. In this paper, we address the question whether isochrons defined by imaging operators can be identified with wavefronts of solutions to an evolution equation. To this end, we consider the double-square-root equation and the space on which its solutions are defined. By manipulating the double-square-root operator, we obtain an evolution equation in two-way time. The propagation of singularities by its solutions is described by extended isochron rays, the corresponding wavefronts of which are extended isochrons. This equation describes prestack depth map migration generating extended (pre-stack) images. Also we foresee possible applications in the illumination analysis in true-amplitude wave-equation depth migration.
