One would think that Project Raster should be used, but it doesn't work with unknown projections. It's intended to change between projections.
What you are looking for is Define Projection. It's designed to work on datasets that don't have a projection.
So, for arcpy, it would be:
Edit:
I'm not sure if there is a programmatical way to define the Raster Coordinate system. I searched and all I found was this, which outlines how to define/modify a raster's coordinate system.
