Figure 1 shows the impulse response of the three residual prestack migration operators [equations (3), (5), (6)].

Figure 1

Figure 1a presents the impulse response for equation (3), with , and .Figure 1b presents the impulse response for equation (5), with and .As expected from the theory discussed in the previous section, Figure 1a and Figure 1b are identical because .

Figure 1c presents the impulse response for equation (6), with , . It is possible to observe the difference with respect to figures 1a and 1b. The difference is due to the approximation in the transformation kernel.

Figure 2 demonstrates the differences between equations (3) and (5). Figure 2a shows the impulse response for equation (3) with, , and .Figure 2b shows the impulse response for equation (5) with, and .It is easy to observe the difference between the impulse responses due to the approximation in the transformation kernel.
