I have read the RISE info at the provided link. It does not explain how those measurements involve radio. Please explain.
Rise uses an X-band Radio for precision Doppler tracking. Since the lander is in a fixed place on Mars, precise tracking of it from Earth can measure small variations in the planet’s rotation, revealing how Mars wobbles as it rotates on its axis.
This info tells scientists about the size and composition of the core and how much it has cooled.
