When migrating more than one shot at the same time, the nonlinearity of the imaging condition causes the final image to contain the so-called crosstalk, i.e., the results of the interference of wavefields associated with different sources. In this work, we study various ideas of using weights in the image condition, called encoding, for the reduction of crosstalk. We combine the ideas of random phase and/or amplitude encoding and random alteration of the sign with additional multiplication withdoi:10.1190/geo2014-0293.1 fatcat:7xcwgjiqefdsvpder6gre3x3qu
