Answer #22

The correct answer is C: CW has a maximal detectable velocity of about 1.5 m/s.

PW has a maximal detectable velocity where it aliases, but CW does not have maximal velocity detection per se. With CW there is constant transmission and receiving of signals (Choice B). The one downside is range ambiguity; you cannot pinpoint the location of the highest velocity along the line of interrogation as you can with PW (Choice A). The Pedoff probe uses only CW (Choice D).
