A wobbulated pulse repetition frequency M.T.I. radar system comprising means carrying out coherent detection of the echo signals, means supplying the differences between successive coherent echo signals of a target and means supplying a weighted sum of two successively supplied differences; the weighting coefficients are so selected that in the resulting sum the spreading of the spectrum of the echoes of the stationary targets, due to the wobbulation, is compensated.
