Multiple imaging is shot-based migration (like shot-based RTM and WEM).

For primary migration, the source side is point source and receiver side is primary data. For multiple imaging, the source side is an array source (primary, down-going wavefield or receiver ghost). So we have 3 types of multiple imaging:

Source side is primary, Receiver side is multiples from SRME

Source side is Down-going wavefield, Receiver side is Up-going wavefield

Source side is receiver ghost wavefield, Receiver side is deghosted wavefield.  It is similar to Up-Down multiple imaging.
