A robust estimation algorithm for the Doppler frequency and its derivatives is proposed based on the MLSAC algorithm. It is shown that it retains its working capacity when the probability of anomalous measurements reaches 0.9 (measurements of the Doppler frequency are abnormal in nine out of ten signal fragments) in comparison with 0.7 for the existing algorithm previously proposed by the authors. This may allow to measure the motion parameters of an object with less visibility at the same distance or an object with the same visibility at a greater distance.
