A novel feature for distinguishing propeller-driven airplanes from turbine-driven airplanes is proposed: the absolute difference between the Euclidean lengths of the amplitude spectrums of two neighboring high-resolution range profiles (HRRP). A preclassification method based on the proposed feature is also presented. Experimental results for measured data verify the efficiency of the proposed feature.
