Canards in mach cone

Hi there,

I am currently looking into designing a guidance module for a mach 1.6 rocket, but I have some questions about the supersonic aerodynamics.

As the canards will be just below the ogive nosecone, I wonder if there is any way they won't be inside the mach cone at all times.

If they are inside the mach cone I reckon they will be in subsonic flow - will I then be able to use the Polhamus equation to calculate?

I'm using the theory from here:

I can see that they are using equations for transonic and supersonic lift as well, but I can't seem to figure out how that is necessary if you'll never get a mach cone smaller than the angle of your canards.

I hope someone can help me out here, cause I am severely confused :)
