The invention relates to a method for detecting and qualifying the state and evolution of a wake turbulence generated by an aircraft from the radar signals reflected by said turbulence, the signals being analysed through analysis cells having given dimensions in terms of distance and relative bearing. The method mainly comprises: a first preliminary detection step strictly for detecting and locating turbulence in a cell; a second step for detecting the force of the detected turbulence; a third step for detecting the age of the detected turbulence and the geometrical parameters characterising the same. The method of the invention can advantageously be used for detecting wake turbulence and determining both the position and the force thereof as well as the evolution stage. The invention canparticularly be used in the field of air traffic control and air security in general.
