I've noticed that MACenc understands the Raymarine MARPA RADAR target messages, but iNavX doesn't show them despte getting the same NMEA feed. I believe the messages are either RSD or TTM.
It'd be great to have them on the iPad, as I often use MARPA to confirm that a shipping I'm seeing really is a particular AIS target

Its definitely the TTM message. If you need examples let me know, but as MACenc understands them - I suspect you already know the contents.

Cheers,
