Good question, and I think that your idea is basically right. I suspect that Cobra is using a separate oscillator for Ka detection since it seems that the other major manufacturers have patents on using harmonics of a single primary oscillator for detection of all radar bands. Maybe some of our forum members who are electronics engineers will chime in with their thoughts.
