For various reasons including meteorite speed and cross section, plus radar scan patterns/rates, back scatter noise filtering software,etc. I don't believe the meteorite/meteoroid-proper is detected via doppler echos. Rather the train/cloud of silicate and iron oxide "fog" expanding to reach thermo-equilibrum in the cold atmosphere that mimics precipitation signatures.
