Figure 5

Area under the ROC curve (AUC) for analyzing the sensitivity to the observation interval length N:  σ _X  = 3 dB, M  = 250, P ₀  = -7 dB and σ _f  = 0 vdB. (a) ROC curves of ${\sigma }_{{\Delta }_{\sigma }}=0$ dB. (b) ROC curves of ${\sigma }_{{\Delta }_{\sigma }}=5$ dB. The plots in this figure are of the area under the ROC curves (AUCs) to analyze the sensitivity to the observation length N. Details about this figure can be found in subsection with the heading Experiment 4 in Section 6.
