    What do you mean by "phantom"? Are you referring to the "mannequins" or "dummies" that are used in place of real people (e.g. in crash testing)? Commented Mar 4, 2016 at 12:06

At the most general term, you would call it a model. An animal model, a mannequin that models human movement/bones/flesh/weight, a drug that models the effects of XYZ in vivo. Whenever we can't use/describe nature directly, we use/describe a model.
