Figure 5From: Classification of ground moving targets using bicepstrum-based features extracted from Micro-Doppler radar signatures Histograms of the second bicepstrum/cepstrum coefficients related to the single (blue), two (red) and three (green) walking persons and computed using: (a) (4) and (b) (5). The histograms show that it is difficult to discern a single walking person from two or three persons by using only this one feature.Back to article page
