Analysis of a Pareto Mixture Distribution for Maritime Surveillance Radar

Figure 4

Comparison of detector performance curves for Pareto and Pareto mixture models. The probability of detection (Pd) is plotted as a function of the signal to clutter ratio (SCR). The optimal detectors are denoted Optimal (PP) for the mixture model and Optimal (P) for the standard Pareto counterpart. The GLRT for the Pareto mixture is denoted GLRT (PP), while the same for a single Pareto model is GLRT (P). The figure shows that the mixture model provides only a very small detection gain.
