We describe a new recursive time imaging method, which is applied over tau-p domain transformed common shot gathers. Although applied in the time domain, the method is capable of correctly image regions with strong lateral contrast in the velocity field, and has operational costs similar to time migration. The velocity model building scheme is equivalent to a recursive standard time migration velocity analysis.
