Disclosed is a method for the suppression by complex conjugate cancellation of unwanted radar echoes caused both by obstacles stationary with respect to the radar transmitter as well as obstacles having a relative speed with respect to the radar transmitter. Cancellation is achieved by the use of a conventional type cancelling operator with at one input a constant weight equal to 1 and at the other input a weight variable in such a way as to make the frequency response of the cancelling operator equal to zero instant-by-instant for a Doppler frequency equal to the average frequency of the unwanted echoes.
