Reverse-time migration (McMechan, 1983) has been widely used
in seismic exploration imaging because of its ability to accurately
implement the two-way wave equation.
The most popular way to implement reverse time migration
is time-extrapolation from the maximum time
to the minimum time with the recorded wave field as
boundary condition.
This algorithm does not pass Claerbout's dot-product test (Claerbout, 1992),
which means that this algorithm is not the conjugate of the time-extrapolation
modeling algorithm.
This paper describes the implementation of a reverse-time migration
algorithm as an exact conjugate operator of the forward time-extrapolation
modeling.
