Double-square-root (DSR) equation describes kinematics of downward data continuation in depth. Corresponding evolution equation in depth and its approximations are used for implementing pre-stack depth migration. The DSR equation is of Hamilton-Jacobi type and can be solved numerically for the whole acquisition system simultaneously. We have developed WENO-RK type numerical solver for DSR equation in curvilinear coordinates. These scheme allows us to compute reflection traveltimes, using the exploding reflector concept. The obtained results could be used for solving different kinematic problems in the presence of topography and high-contrast reflectors.
