Passive imaging by surf noise autocorrelation

What is it about?

Passive imaging is defined as a technique wherein waves recorded at two receiver locations are correlated to give the Green's function that describes the direct wave propagation between these receivers. In this paper, we got the experiment result which give the Green's function by one receiver autocorrelation.

Why is it important?

In fact, the Green's function extraction by noise autocorrelation was first proposed by claerbout in 1968, but good experiment result was by using noise cross correlation. In this paper,we give a good experiment result by using noise autocorrelation。
