Yes. The Zeus radar was, back in the days of wave propagation storage (they literally used a tube of mercury to store an analog signal while other computing operations were carried out - this was a long time ago) and ferrite core RAM, was able to do this by filtering objects based on velocity change.
Radars are stupidly advanced, now. We can pick up the reflections from cell phone towers if we really want to and can even profile aircraft in the same way submarines profile individual ships. We can count turbine blades in the reflected signal.
And that is before getting into plasma lenses, which allow us to lens microwaves and even amplify signals using plasma, itself. Though that is all research and pre-market tech that the civilian world knows by white paper and a few basic university trials with the concept.
Chaff and radar balloons in MIRVs were obsolete before the mirv was realized. We designed the Zeus radar complex to be able to decipher just that and could track hundreds from thousands of potential returns at each station. In the 50s.
