A device for processing radar signals which enable precise Doppler information to be obtained. The signals, demodulated in cartesian coordinate X and Y and then coded are converted into polar coordinate rho and theta . Then theta is replaced by the difference theta ' between two successive values of theta received during two consecutive repetitions. The couple rho , theta ' is converted into cartesian coordinate X' and Y', filtered and then reconverted into polar coordinate rho '' and theta '' where rho '' represents the amplitude relative to the echo and theta '' its Doppler speed.
