Examples of performance of the CFAR ( 17), which is denoted by ANMF Approx in the figure. In all cases, the four other detectors have had their thresholds set so that they have the same false alarm probability as in (17). The left subplot is for the case where N=20,ρ=0.5 and false alarm probability is 10−6. The CFAR (17) is such that the Pareto shape parameter is overestimated by double, while the scale parameter is underestimated by 20%. We observe that the detector (17) has performance bounded by that of the ANMF and NMF. The right subplot corresponds to N=10,ρ=0.5 and a false alarm probability of 10−7. Here, it is assumed that the shape parameter is overestimated by triple, and the scale parameter is overestimated by double. In this case, the detectors have closer matched performance, while the NMF saturates.
