“…Among several radar signatures, the range profile (RP) shows the unique one dimensional distribution of the radar cross-section [2][3][4][5][6][7][8][9] of the automobile and can be effectively used for classification of automobiles which can contribute to anti-collision, lane-change, and automobile control regardless of weather and day-night conditions [10]. RP can also provide two-dimensional radar image of automobiles if the synthetic aperture radar (SAR) [11][12][13][14][15][16][17][18], the inverse SAR [19] and the jet engine modulation [20] techniques are applied.…”

Abstract-The range profile (RP) of an automobile is derived by compressing the wideband radar signal, and it can be utilized for the classification and thus contribute to lane change and collision avoidance. However, the limited radar bandwidth due to the cost and the system complexity impedes the successful classification. This paper proposes an efficient method to construct an efficient feature vector of the automobile RP through combined use of the central moment, the information on the maximum-minimum and the peak information. Simulation results using the five automobile models composed of point scatterers and a simple nearest neighbor classifier prove that the proposed method improves the classification result, especially in the multi-aspect classification.
