Figure 8

Analysis of the CFAR detector (17) in the same clutter environment as for Figure 7 . The left subplot is for the case where N=40,ρ=0.6 and false alarm probability is 10−5. It is assumed that the parameter α is underestimated by 20%, while β is overestimated by 20%. We see that the new CFAR has very good performance. The right subplot is for N=30,ρ=0.1 and a false alarm probability of 10−7. For this example, the Pareto shape parameter is overestimated by 80%, while the scale parameter is overestimated by 20%. As before, the new CFAR has excellent performance.
