Not really. It was first described as such by Christian Doppler (hence the name), who noted that from the perspective of a "stationary" observer, the apparent pitch of the whistle of a train rose as the train approached, but fell as the train departed. Thus, it is an apparent frequency-shift that depends on the relative velocities of the source of a wave and the observer.
