The back of the dish could be obscured by the rest of the ship's
hull.  For example, the hull could be shaped like a tetrahedron.
One face has the radiator dish in it.  Another face is toward
the Sun.  That face reflects sunlight into a narrow cone in an
arbitrary direction vaguely toward the Sun.  Due to the
reflectivity of the faces, this hull will show up well on radar
and really well on radar at wavelengths comparable to the
hull diameter.  But as for passive visible/IR sensors, the ship
could be pretty stealthy (assuming the existence of the
broadband uber-reflective material).
