A method for the acoustic recognition of aircraft types and flight patterns is presented, in which a discriminatory analysis slightly different from the ordinary one is used and peak-hold spectra (one-third octave band) relative to the peak value of A weighted sound pressure levels are selected for characteristic parameters of reference patterns. The newly developed procedure proved to be able to recognize aircraft types and flight patterns accurately irrespective of the mission of an airfield. Only a small number of parameters are required in the procedure.
