You can do that on a router table, but it's a bit tedious.
First, do the profile details on the sides of the center arc. You're drawing shows simple rabbets, but the picture looks like coves?
Once those are done, make a series of passes with a core box bit. Start with a 1/4" bit at the edges, and move the fence about 1/16 (or less) per pass, adjusting the depth of cut as required. When you get enough room, switch to a 1/2" core box bit. The larger diameter will give you a smoother finish, requiring less sanding.
This is the manual version of how I make custom mouldings on a CNC router. Exact small technique, just a different tool.
