"Doppler Radar" is a very touted "TV" technology since 1991, yet very rarely presented since since most people have very little interest or training in the interpretation of radial velocities to/from any given radar transmitter.
What most "TV" and apps present is reflective DBz values based on simple particle size and composition (water solid/liquid), not radial "Doppler" velocities based on speed toward or away from the transmitter.
Current 88D software modelling and output requires formal training and educated interpretation to understand any meteorological implications. By far, the very vast majority of "TV"/web reporters and apps have no such formal training to understand what it means, yet they love to use the word "Doppler" -- Caveat Emptor.
