Apr 10, 2019 at 6:08 comment added Mohammad Golshani For ordinary Radin forcing, you can preserve all supercompactness even, see Radin's paper (he shows you can preserve $\lambda$-supercompactness). My paper with Gitik also uses the ordinary Radin forcing and not its supercompact version. Similar facts about strong cardinals.
Apr 10, 2019 at 6:04 comment added Jiachen Yuan Thanks for the references. I'm sorry for the ambiguity of my question. What I actually want to know is that, when you have a supercompact $\kappa$, but you can only use the measure sequence on $V_\kappa$ (i.e. not the supercompact Radin forcing associate to $P_\kappa(\lambda)$), how much strength can you preserved, can you find a particular length to show that $\kappa$ is strong.
